Tell us about your team, your school!
+
The Hewitt-Trussville High School team consists of seven students in the Biomedical Sciences Academy. Trussville, Alabama is rural community of approximately 20,000 people found eighteen miles northwest of Birmingham in Jefferson County, and Hewitt-Trussville High School has approximately 1300 students. Over the last four years, we have navigated our way through the Project Lead The Way biomedical sciences curriculum and worked together in labs. The seven members of our team are all 2014 seniors including Jessica Bacon, Darcy Echols, Nicole Hardesty, Nikki Newman, Sikandar Raza, Connor Staggs, and Chloe Wilks. We also have an amazing mentor from the Hudson-Alpha Institute of Biotechnology, Dr. Bob Zahorchak. But, most importantly, we want to save the endangered snail populations in the Cahaba River by developing a cheap and efficent phosphate detection plasmid for the Alabama Department of Environmental Managaement to use.

October 3, 2013:
 +
 +
Questions:
 +
 
 +
1) Is phosphate consistent throughout a river or are there different concentrations at certain spots?
 +
 
 +
2) Orthophosphate vs. Polyphosphate
 +
 
 +
3) Pho 89, Pho84”p”, and Pho87/Pho90
 +
 
 +
4) Are there more sensors than just those?
 +
 
 +
5) Target the transmitters so there could be a more colored result for the phosphate levels.
 +
 
 +
6) Will the stored phosphate in the vacuoles affect our plasmid?
 +
 
 +
7) Pho84 and excess amounts of phosphate
 +
 
 +
8) Could we turn off/bypass Pho4
 +
 +
9) Increase CDK?
 +
 
 +
10) How does the algae know that phosphate is in the water? Possible back up?
 +
 
 +
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
Answers Dr. Zahorchak:
 +
 
 +
Ortho PO4-2  vs. Poly PO4-2
 +
                        OH
 +
        |   Ortho: 2PO4-2 attached to each other
 +
(bases sugar)--OH--P=O
 +
          |
 +
        OH
 +
 
 +
Why trying to engineer these systems?  ⇇
 +
 
 +
Detect PO4-2 (if it is present)
 +
 
 +
fertilizer has a lot of PO4-2
 +
 
 +
 
 +
Check latest ADEM reports for water quality
 +
 
 +
How to detect levels?
 +
 
 +
Determine sensitivity (down the road)
 +
 
 +
What level will it switch on/off
 +
 
 +
Qualitative data first
 +
 
 +
Stored PO4-2 in a cell vacuole? Does that affect the test?
 +
 
 +
Yes
 +
 
 +
Think of a way to grow the yeast so that the cell can’t store subsistence in the vacuole (not a major priority right now)
 +
 
 +
Make both programs compatible to use
 +
 
 +
Pick One
 +
    GENtle
 +
 
 +
 
 +
Wait to measure different levels of color
 +
 
 +
Increase CDK?
 +
        Do not want to mess with this
 +
        Learn more about
 +
 
 +
Yeast Transformation Lab?
 +
        Either make your own kit or buy competent cells (pros/cons)
 +
        Competent Cells
 +
                  Using antifungal to kill yeast that do not accept the plasmid
 +
 
 +
Check biobricks for the yeast and vector
 +
 
 +
Check for yeast iGEM projects from before/previous years
 +
 
 +
iGEM material=free
 +
 
 +
Make a list of what we need
 +
 
 +
Include sequences
 +
 
 +
What is this?
 +
        Restriction Enzymes
 +
 
 +
 
 +
 
 +
 
 +
Notes from Dr. Zahorchak:
 +
 
 +
Pho5 regulates phosphotase
 +
 
 +
What enzyme(s) are included in the pathway?
 +
 
 +
What if one of the sites you need is internal to Pho5?
 +
 
 +
Find Pho5 promoter (BLast)
 +
 
 +
Might need to find the exon.
 +
 
 +
Need the entire Pho5 promoter
 +
 
 +
Figure out if everything is on the RFP after Pho5 gene is fused
 +
 
 +
 
 +
 
 +
Answers from Dr. Zahorchak (continued):
 +
 
 +
Chemical test
 +
      Converts PO4 to ortho
 +
 
 +
Would our test look for orthophosphate or all forms?
 +
 
 +
Test strips ($6) only test for ortho
 +
Chemical test ($45) converts all forms of phosphate into orthophosphate then tests
 +
 
 +
Goals Before Christmas:
 +
 
 +
1)Finish Research
 +
 
 +
2)plug everything into GENtle and run simulations

 +
Pho5 not made in high phosphate?
 +
-See Figure 5
 +
 
 +
Low Phosphate
 +
-See Figure 6
 +
*See Figure 7: Starvation Pathway
 +
The yeast already makes RFP so it would already be red.
 +
 +
Grow it in high Phosphate
 +
 
 +
Don’t worry about fusing RFP to Pho5
 +
-See Figure 8
 +
 
 +
 
 +
 
 +
Stop codons/terminator sequence: Biobricks site
 +
 
 +
Where does RFP come from? Jellyfish?
 +
 
 +
Make sure codon sequence for RFP works in yeast
 +
 
 +
 
 +
November 4, 2013
 +
 
 +
Use shuttle vector and grow in E.coli
 +
      Needs origin of replication
 +
 
 +
E. coli does not produce protein that regulates Pho5
 +
      Compatible origin for yeast and E.coli
 +
          So, no phosphate in E.coli
 +
 
 +
Construct plasmid in vector
 +
    Put in E.coli→ verify by PCR. Does it work?
 +
 
 +
Plasmid has gene to make enzyme so that transformants will grow.
 +
    Select Transformants
 +
    Uracil metabolism
 +
          Check out white/red colonies
 +
 
 +
Find a selectable marker on plasmid
 +
    Get the right yeast strain
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +

November 5, 2013
 +
 
 +
1) ORI E.coli
 +
 
 +
2) ORI Yeast
 +
 
 +
3) Pho5 Promoter
 +
 
 +
4) RFP
 +
 
 +
5) Ampicillin Resistant
 +
-See Figure 9
 +
 
 +

Meetings with Dr. Zahorchak
 +
 
 +
Plasmid each time/change
 +
 
 +
Notes on findings/changes
 +
 
 +
 
 +
 
 +
November 6, 2013
 +
To Do:
 +
 
 +
1) Verify that plasmid ORI sites for yeast and E.coli are present
 +
 
 +
2) If yeast is present match yeast type to ORI type
 +
 
 +
3) Find restriction enzyme that will make sticky end cut (after Pho5 promoter) that works with RFP, but only cuts beginning of RFP.
 +
 
 +
4) Continue research for plasmid
 +
 
 +
 
 +
November 12, 2013
 +
 
 +
Possible plasmid found
 +
      pJRL2-PHO5prVYFP
 +
 
 +
Already contains Pho5 promoter, but will need RFP and antifungal genes inserted.
 +
      Insertion will most likely be done with Gibson Assembly
 +
 
 +
-See Figure 10
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
Talk with Dr. Zahorchak:
 +
       
 +
Decided it best to not use this plasmid as the final construct
 +
              Best to create our own
 +
 
 +
Instead this plasmid will be used for the Pho5 promoter
 +
            Cut Pho5 promoter out using restriction enzymes
 +
                    BamHI
 +
                    EcoRI
 +
            Adapters will be used to make the Pho5 compatible with iGEM standards (since RFP will come from iGEM database)
 +
 
 +
Continue looking for a suitable plasmid
 +
 
 +
 
 +
November 13, 2013
 +
Old Plasmid:
 +
 
 +
 
 +
 
 +
-See Figure 11
 +
 
 +
 
 +
 
 +
 
 +
 
 +
Must have in new plasmid:
 +
ORI- E.coli
 +
ORI- Yeast
 +
Ampicillin resistance
 +
Pho5 promoter
 +
RFP
 +
 
 +
Possible New Plasmid:
 +
 
 +
 
 +
 
 +
-See Figure 11
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
 
 +
To Do’s:
 +
Look at shuttle vectors on iGEM
 +
Relook at Pho5 promoter
 +
Methods:
 +
Ligation
 +
Competent Cells
 +
Conjugation
 +
 
 +
 
 +
November 15, 2013
 +
 
 +
Plasmid search still ongoing, but after a talk with Dr. Zahorchak what to look for is more clear.
 +
      pUC ORI= E.coli ORI
 +
      2u origin= Yeast ORI
 +
      Amp. marker
 +
      Selection marker for yeast
 +
              Decided to use a yeast antibiotic, such as G418, instead of an antifungal
 +
 
 +
Questions to Answer:
 +
 
 +
1) What is the DNA sequence of each part? How will each part be obtained? If using PCR for parts what will be the primer sequence?
 +
 
 +
2) Sequences have all been found. Most parts will come from the registry and others synthesized. The parts that require PCR will have primers ordered with them. Primers come with parts from registry.
 +
 
 +
3) How will the pieces be put together?
 +
 
 +
4) Further research has shown that 3A Assembly is more effective than Gibson so 3A will now be used. Once a plasmid is found, adapters will be designed to link all parts for insertion.
 +
 
 +
5) How do you assure that the parts will assemble in the correct order?
 +
 
 +
6) The adapters will be designed to ensure the parts go where desired.
 +
 
 +
7) How will sequence orders be verified?

November 25, 2013:
 +
Discussion with Dr. Zahorchak
 +
 +
Since Pho5 is being cut from another vector, it will need to be PCRed.
 +
 
 +
Primers will be worked on at a later date
 +
 
 +
Most likely in person to be checked.
 +
 
 +
Final plasmid will be first grown in E.coli because the transformation is easier making checking for the construct easier.
 +
 
 +
The final plasmid will be then transfigured to yeast for final product and final testign.
 +
 
 +
Need to make sure the promoter will control the RFP.
 +
 
 +
Check end sequence for compatibility.
 +
 
 +
COMPATIBLE OVERHANGS ARE NEEDED.

Plasmid problem:
 +
  The desired part from the registry was never submitted/unavailable
 +
 
 +
Possible Plans:
 +
  Use blank shuttle vector (contains E.coli ORI and Amp) and insert everything (Pho5 promoter, RFP, and G418) except yeast ORI
 +
  Addition of yeast ORI exceed our current means so it would have to be done in the future
 +
  Search for a new plasmid that contains the basics (E. coli and yeast ORI, Amp resistance, and preferably G418)
 +
  E-mail original creator to request a copy of the plasmid.
 +
 
 +
January 16, 2014
 +
The Plan:
 +
  Continue working as before and expect to us a blank shuttle vector.
 +
  Yeast ORI can be added in the future by another group if need be
 +
  While working, do brief research on any available plasmids with both ORI’s
 +
 
 +
January 21, 2014
 +
  A new plasmid has been found! It contains a yeast and E.coli ORI, Amp, and G418 (KanMX). Only Pho5 and the RFP will have to be added, but all new adapter will have to be created.
 +
  Dr. Z was able to find a colleague that had this plasmid on hand; he will deliver it to us in E.coli in order to start the process.
 +
 
 +
  Insert parts after SacI restriction sight

===Results/Conclusions===
-
What did you achieve over the course of your semester?
+
Over the past semester, we were able to take a years worth of research and begin experimenting. We were able to work through and learn from our mistakes to help make our project a success. Though the plasmid may not be finished, by reaching the final step of ligation, we are able to make plans to proceed forward in the future.
===Safety===
===Safety===
-
What safety precautions did your team take? Did you take a safety training course? Were you supervised at all times in the lab?
+
 +
Q1.
 +
Ans.
 +
·      E.Coli was used in this experiment as a rapid growth mechanism before the shuttle vector was palced into yeast. E.Coli is a biosafety level 1 organism, as natonal stnadards of this organism characterizes this organism as not known to consistently cause disease in healthy adults. By this standard it is recommended for those coming in contact that they where lab coats, eye protection, and gloves.
 +
·      If project goes according to plan, team member, the public, and the environment will face no risks. Proper lab equipment, such as an autoclave, and protective-wear, such as gloves and lab coats, will be essential to allow no risk. Through lab safety training every year in high school showing lab-safety procedures and handling of various apparatus.
 +
·      If proper lab-safety procedures are not followed, then the E.Coli has the potential to enter a physical opening in a group member, which will place the group member at risk for illness.  If this interaction occurs, the group member will be transported to the hospital for a check-up with his/her doctor to ensure no potential health risk.
 +
 +
Q2.
 +
Ans.
 +
·      No parts were submitted to the registry.
 +
 +
Q3.
 +
Ans.
 +
·      The Trussville City Schools Board of Education is our local biosafety group, and they are in support of the materials and methods that use the bio-hazardous organisms.
 +
Q4.
 +
Ans.
 +
For future teams, opening registration earlier, as well as sending out kits earlier would be helpful for a quicker and more accurate route to success.

-
Who worked on what?
+
The lab work as well as research was split up evenly amongst group members. Dr. Zahorchak and Mr. Walters served only as mentors and guidance, listening to our ideas, but never placing their own upon us. They gave us space to work and perform our project but were never truly, physically involved in any lab work or research.
===Human Practices===
===Human Practices===
-
What impact does/will your project have on the public
+
Our project will allow a safer way to test for phosphate levels. Current tests include harmful, poisonous chemicals. This test will also make the public aware of the runoff that they are placing in their streams, harming the aquatic life.

Official Team Profile

Team

The Hewitt-Trussville High School team consists of seven students in the Biomedical Sciences Academy. Trussville, Alabama is rural community of approximately 20,000 people found eighteen miles northwest of Birmingham in Jefferson County, and Hewitt-Trussville High School has approximately 1300 students. Over the last four years, we have navigated our way through the Project Lead The Way biomedical sciences curriculum and worked together in labs. The seven members of our team are all 2014 seniors including Jessica Bacon, Darcy Echols, Nicole Hardesty, Nikki Newman, Sikandar Raza, Connor Staggs, and Chloe Wilks. We also have an amazing mentor from the Hudson-Alpha Institute of Biotechnology, Dr. Bob Zahorchak. But, most importantly, we want to save the endangered snail populations in the Cahaba River by developing a cheap and efficent phosphate detection plasmid for the Alabama Department of Environmental Managaement to use.


Due to rising use of chemical based fertilizers, the runoff of harmful chemicals such as phosphate (PO43-) and nitrate (NO3-) into public water sources has increased. This accumulation of chemicals in streams and lakes is harmful to the environment. PO43- runoff in rivers is detrimental to aquatic life forms such as the Leptoxis compacta, a gastropod that was believed to have been extinct in 2000; however, in May of 2011 the Leptoxis compacta was rediscovered in the Cahaba River. PO43- is a food source for algae and as the levels of PO43- increase, the number of algae blooms increase and cover the surface of the water. This blocks sunlight so the energy cannot get to the bottom of the river. Currently tests are chemical in nature and specific to only certain forms of PO43- (testing only organic phosphate or orthophosphate). This research revolves around the creation of a biological plasmid to test for all forms of PO43- in a sample of water. Using a shuttle vector, the plasmid is first grown in E. coli, and then transferred into a specific type of yeast called S. cerevaise, which contains an outer sensor for PO43- .The sensor tests for the presence of PO43- because it is a food source for the yeast. If PO43- is present, then the yeast uses it for energy development; however, if no phosphate is present in the environment, then the sensor sends a cascading signal to a protein called Pho4, which binds to a gene called Pho5 to initiate the phosphate starvation cycle. This mechanism allows the yeast to produce its own phosphate.

The plasmid that is inserted into S. cerevaise contains the genetic sequence for the Pho5 promoter that when activated will turn on a Red Florescent Protein (RFP). The Pho5 promoter will be removed from one plasmid using the restriction enzymes EcoRI and BamHI. An adaptor will then be used to convert the sticky end produced by BamHI into a second compatible EcoRI sticky end. After performing Polymerase Chain Reaction, this fragment of DNA will then be inserted into a new plasmid using 3A assembly. The new plasmid will already posses the RFP gene and antibiotic resistance which will be used to make competent cells. The recombinant plasmid will then be grown in E. coli before being shuttled into the yeast cells. The Pho5 promoter in the new plasmid will then be able to receive the Pho4 protein if it is initiated when PO43- is not present. When the Pho4 is bound to the Pho5 on the plasmid, the RFP gene will be activated. The RFP will cause the yeast to turn bright red, signaling that there is no PO43- present; if the yeast does not turn bright red, then PO43- is present in the environment. Therefore the plasmid serves as a qualitative and quantitative method to test for the presence of PO43- in a water sample, which in turn creates a biological mechanism that is not hazardous to monitor levels of PO43- .

October 3, 2013:

Questions:

1) Is phosphate consistent throughout a river or are there different concentrations at certain spots?

2) Orthophosphate vs. Polyphosphate

3) Pho 89, Pho84”p”, and Pho87/Pho90

4) Are there more sensors than just those?

5) Target the transmitters so there could be a more colored result for the phosphate levels.

6) Will the stored phosphate in the vacuoles affect our plasmid?

7) Pho84 and excess amounts of phosphate

8) Could we turn off/bypass Pho4

9) Increase CDK?

10) How does the algae know that phosphate is in the water? Possible back up?






Answers Dr. Zahorchak:

Ortho PO4-2 vs. Poly PO4-2 OH | Ortho: 2PO4-2 attached to each other

(bases sugar)--OH--P=O

| OH

Why trying to engineer these systems? ⇇

Detect PO4-2 (if it is present)

fertilizer has a lot of PO4-2


Check latest ADEM reports for water quality

How to detect levels?

Determine sensitivity (down the road)

What level will it switch on/off

Qualitative data first

Stored PO4-2 in a cell vacuole? Does that affect the test?

Yes

Think of a way to grow the yeast so that the cell can’t store subsistence in the vacuole (not a major priority right now)

Make both programs compatible to use

Pick One

    GENtle


Wait to measure different levels of color

Increase CDK?

       Do not want to mess with this
       Learn more about

Yeast Transformation Lab?

        Either make your own kit or buy competent cells (pros/cons)
        Competent Cells
                 Using antifungal to kill yeast that do not accept the plasmid

Check biobricks for the yeast and vector

Check for yeast iGEM projects from before/previous years

iGEM material=free

Make a list of what we need

Include sequences

What is this?

       Restriction Enzymes 



Notes from Dr. Zahorchak:

Pho5 regulates phosphotase

What enzyme(s) are included in the pathway?

What if one of the sites you need is internal to Pho5?

Find Pho5 promoter (BLast)

Might need to find the exon.

Need the entire Pho5 promoter

Figure out if everything is on the RFP after Pho5 gene is fused


Answers from Dr. Zahorchak (continued):

Chemical test

     Converts PO4 to ortho

Would our test look for orthophosphate or all forms?

Test strips ($6) only test for ortho Chemical test ($45) converts all forms of phosphate into orthophosphate then tests

Goals Before Christmas:

1)Finish Research

2)plug everything into GENtle and run simulations

3)materials

4)methods (plasmid methods)

5)Begin Plasmid construction

October 23, 2013 Pho5 not made in high phosphate? -See Figure 5

Low Phosphate -See Figure 6

  • See Figure 7: Starvation Pathway

The yeast already makes RFP so it would already be red.

Grow it in high Phosphate

Don’t worry about fusing RFP to Pho5 -See Figure 8


Stop codons/terminator sequence: Biobricks site

Where does RFP come from? Jellyfish?

Make sure codon sequence for RFP works in yeast


November 4, 2013

Use shuttle vector and grow in E.coli

     Needs origin of replication

E. coli does not produce protein that regulates Pho5

     Compatible origin for yeast and E.coli 
         So, no phosphate in E.coli

Construct plasmid in vector

    Put in E.coli→ verify by PCR. Does it work?

Plasmid has gene to make enzyme so that transformants will grow.

    Select Transformants 
    Uracil metabolism 
          Check out white/red colonies

Find a selectable marker on plasmid

    Get the right yeast strain 






November 5, 2013

1) ORI E.coli

2) ORI Yeast

3) Pho5 Promoter

4) RFP

5) Ampicillin Resistant -See Figure 9




Meetings with Dr. Zahorchak

Plasmid each time/change

Notes on findings/changes


November 6, 2013 To Do:

1) Verify that plasmid ORI sites for yeast and E.coli are present

2) If yeast is present match yeast type to ORI type

3) Find restriction enzyme that will make sticky end cut (after Pho5 promoter) that works with RFP, but only cuts beginning of RFP.

4) Continue research for plasmid


November 12, 2013

Possible plasmid found

     pJRL2-PHO5prVYFP

Already contains Pho5 promoter, but will need RFP and antifungal genes inserted.

     Insertion will most likely be done with Gibson Assembly 

-See Figure 10




Talk with Dr. Zahorchak:

Decided it best to not use this plasmid as the final construct

             Best to create our own

Instead this plasmid will be used for the Pho5 promoter

            Cut Pho5 promoter out using restriction enzymes
                    BamHI
                    EcoRI
           Adapters will be used to make the Pho5 compatible with iGEM standards (since RFP will come from iGEM database)

Continue looking for a suitable plasmid


November 13, 2013 Old Plasmid:


-See Figure 11



Must have in new plasmid: ORI- E.coli ORI- Yeast Ampicillin resistance Pho5 promoter RFP

Possible New Plasmid:


-See Figure 11





To Do’s: Look at shuttle vectors on iGEM Relook at Pho5 promoter Methods: Ligation Competent Cells Conjugation


November 15, 2013

Plasmid search still ongoing, but after a talk with Dr. Zahorchak what to look for is more clear.

      pUC ORI= E.coli ORI
      2u origin= Yeast ORI
      Amp. marker
      Selection marker for yeast 
             Decided to use a yeast antibiotic, such as G418, instead of an antifungal 

Questions to Answer:

1) What is the DNA sequence of each part? How will each part be obtained? If using PCR for parts what will be the primer sequence?

2) Sequences have all been found. Most parts will come from the registry and others synthesized. The parts that require PCR will have primers ordered with them. Primers come with parts from registry.

3) How will the pieces be put together?

4) Further research has shown that 3A Assembly is more effective than Gibson so 3A will now be used. Once a plasmid is found, adapters will be designed to link all parts for insertion.

5) How do you assure that the parts will assemble in the correct order?

6) The adapters will be designed to ensure the parts go where desired.

7) How will sequence orders be verified?

8) Horizontal gel electrophoresis will be run against a control.






November 18, 2013

Plasmid found

    Contains both ORI’s, G418 (URA3 gene), and Amp
            iGEM compatible/registry compatible  
            Also contains an RFP 
            Pho5 will be inserted 
            Research on G418
                  Aminoglycoside antibiotic
                         Blocks polypeptide synthesis by inhibiting the elongation step in cells.
                         Recommended concentration in yeast cells is 500-1000 mg/ml
                         Resistance is confirmed by the neo gene from Tn5 encoding an aminoglycoside  3’-phosphotransferase ATP 3’11

-See Figure 12








November 25, 2013: Discussion with Dr. Zahorchak

Since Pho5 is being cut from another vector, it will need to be PCRed.

Primers will be worked on at a later date

Most likely in person to be checked.

Final plasmid will be first grown in E.coli because the transformation is easier making checking for the construct easier.

The final plasmid will be then transfigured to yeast for final product and final testign.

Need to make sure the promoter will control the RFP.

Check end sequence for compatibility.

COMPATIBLE OVERHANGS ARE NEEDED.


December 16, 2013: Adapters: Very small piece of DNA with one restriction site on each end. Convert BamHI restriction enzyme site on Pho5 promoter, to and EcoRI site for insertion to plasmid (from database) and attachment to RFP.

BamHI:

-See Figure 13


EcoRI: -See figure 14

Decided on adapter sequence -See Figure 15

Order sequence from New England Biolabs

December 20, 2013 Create methods for:

  Plasmid extraction 
  3A assembly 
  Adding adapters 
  Ligation 
  Transformation 
  Transfiguration 
  PCR
  Create supply list

2014

January 15, 2014

Plasmid problem:

  The desired part from the registry was never submitted/unavailable

Possible Plans:

  Use blank shuttle vector (contains E.coli ORI and Amp) and insert everything (Pho5 promoter, RFP, and G418) except yeast ORI
  Addition of yeast ORI exceed our current means so it would have to be done in the future
  Search for a new plasmid that contains the basics (E. coli and yeast ORI, Amp resistance, and preferably G418)
  E-mail original creator to request a copy of the plasmid.

January 16, 2014 The Plan:

  Continue working as before and expect to us a blank shuttle vector.
  Yeast ORI can be added in the future by another group if need be
  While working, do brief research on any available plasmids with both ORI’s

January 21, 2014

  A new plasmid has been found! It contains a yeast and E.coli ORI, Amp, and G418 (KanMX). Only Pho5 and the RFP will have to be added, but all new adapter will have to be created. 
  Dr. Z was able to find a colleague that had this plasmid on hand; he will deliver it to us in E.coli in order to start the process. 
  Insert parts after SacI restriction sight
  • See Figure 15*

January 27, 2014

New adapter sequence have been created for Pho5 and RFP

  Adapter A:
  Attached to the 5’ end of the Pho5 promoter and will be attached to the plasmid pUG6
  • See Figure 16*




Adapter B: Attached to plasmid pUG6

  • See Figure 17*

Adapter C: Attached to the 3’ end of the Pho5 promoter and the 5’ end of the RFP (where RFP and Pho5 attach)

  • See Figure 18*

Adapter D: Attached to the 3’ end of the RFP and the 5’ end of Adapter B

  • See Figure 19*

Plasmid→A→Pho5→C→RFP→D→B→Plasmid




February 3, 2014

  Plasmid in E. coli and extraction methods have been received
  Process will begin after the next conference with Dr. Zahorchak to ensure everything is present
  • See Figure 20*

February 10, 2014

Extraction process has begun
  3 different method being used
  A single colony of E. coli was mixed with the solution and shaken at room temp for 24hrs; Another was in an incubator for 24 hours; Another was heated and shaken.

February 17, 2014

  A buffer is missing as well as ampicillin from plasmid prep kit
  Snow days invalidated experiment so it must be redone
  Will be started after a meeting with Dr. Zahorchak to pick up missing items

February 18, 2014

  Meeting with Dr. Zahorchak a success. All necessary items are present and accounted for. 
  The extraction process has been started once again
  Two samples (E.coli colonies) were incubated for 24hrs while in the solution then underwent standard protocol. 
  Another two were shaken at room temperature for 24hrs before undergoing standard protocol.
  Different methods were used for the prep to see which were the most effective.

February 19, 2014

  Extraction has been finished. All checkpoints have been met so far.
  A gel will be run in the morning to check accuracy.

February 20, 2014

  Analyzed the gel with LoggerPro 
  Extraction was a success
  Samples shaken at room temperature for 24hrs were the most successful 
     .5% and 1.0% error showing the successful extraction of the plasmid from E. coli 

Next Steps:

  Once supplies arrive-
  Extract RFP and Pho5
  Attach adapters
  Attach Pho5 and RFP
  Insert into plasmid
  Insert into E. coli
  Transform into yeast
  Note these are very general and not step by step methods

Results/Conclusions

Over the past semester, we were able to take a years worth of research and begin experimenting. We were able to work through and learn from our mistakes to help make our project a success. Though the plasmid may not be finished, by reaching the final step of ligation, we are able to make plans to proceed forward in the future.


Safety

Q1. Ans. · E.Coli was used in this experiment as a rapid growth mechanism before the shuttle vector was palced into yeast. E.Coli is a biosafety level 1 organism, as natonal stnadards of this organism characterizes this organism as not known to consistently cause disease in healthy adults. By this standard it is recommended for those coming in contact that they where lab coats, eye protection, and gloves. · If project goes according to plan, team member, the public, and the environment will face no risks. Proper lab equipment, such as an autoclave, and protective-wear, such as gloves and lab coats, will be essential to allow no risk. Through lab safety training every year in high school showing lab-safety procedures and handling of various apparatus. · If proper lab-safety procedures are not followed, then the E.Coli has the potential to enter a physical opening in a group member, which will place the group member at risk for illness. If this interaction occurs, the group member will be transported to the hospital for a check-up with his/her doctor to ensure no potential health risk.

Q2. Ans. · No parts were submitted to the registry.

Q3. Ans. · The Trussville City Schools Board of Education is our local biosafety group, and they are in support of the materials and methods that use the bio-hazardous organisms. Q4. Ans. For future teams, opening registration earlier, as well as sending out kits earlier would be helpful for a quicker and more accurate route to success.


Attributions

The lab work as well as research was split up evenly amongst group members. Dr. Zahorchak and Mr. Walters served only as mentors and guidance, listening to our ideas, but never placing their own upon us. They gave us space to work and perform our project but were never truly, physically involved in any lab work or research.


Human Practices

Our project will allow a safer way to test for phosphate levels. Current tests include harmful, poisonous chemicals. This test will also make the public aware of the runoff that they are placing in their streams, harming the aquatic life.


Fun!

Our team spent many hours working hard on research and notes at Starbucks, so naturally scones and coffee were our favorite snack.
