CLONING THE TOP10 STRAINS
TRANSFORMATION
Plasmids containing the BBa_K1291071 (Horseradish peroxidase composite part) and BBa_K1291299 (Lignin Peroxidase composite part) parts were transferred into our T10 strains, which were prepared through the competent cell preparation protocol, using transformation protocols. Colonies were seen in agar plates that had the appropriate antibiotics after a 16 hour long incubation process.
PLASMID ISOLATION
The
colonies taken from plates were incubated in LB Broth containing AMP for 16
hours. DNA isolation was done on the bacteria culture to check the efficiency.
The adequacy of the amount of the nucleic acid concentration for digestion was
met in the acquired samples and it was seen that the samples had peaks at OD
260, which was captured by the nanodrop.
Digestion and DNA Electrophoresis
Gel electrophoresis was conducted on the samples so that the enzymes which were digested with the EcoRI and PstI could be verified in terms of their wavelength. The acquired results showed that the plasmid transfer process was successful for the Top10 strains while the NEB10 strains, which were taken from the stock, were disfunctional thus were unusable.
CLONING THE BL-21 STRAINS
Since we require a high concentration of proteins in our project, we decided to use the BL-21 strain of E.coli instead of Top10 strains due to its enhanced protein synthesis capacity. Plasmids containing the BBa_K1291071 (Horseradish peroxidase composite part) and BBa_K1291299 (Lignin Peroxidase composite part) parts were transferred into our BL-21 strains, which were prepared through the competent cell preparation protocol, using the transformation protocol. The colonies successfully acquired after a 16-hour long incubation process.
PLASMID
ISOLATION
The
chosen colonies were incubated for 16-hours in AMP containing LB Broth. DNA
Isolation was done to test the efficiency of the transformation. A peek at OD
260 was observed and sufficient levels of DNA concentration was acquired to
continue to digestion.
Digestion and DNA Electrophoresis
Gel electrophoresis was conducted on the samples so that the enzymes which were digested with the EcoRI and PstI could be verified in terms of their wavelength. The acquired results showed that the plasmid transfer process was successful for BL-21 Strains and it was possible to continue to the next step.
