CRISPR-Cas9 based system offers several advantages including greater flexibility in silencing and repairing gene expression, and the ability to introduce larger gene fragments. The system was designed to have great compatibility with a wide range of organisms and easy to work with, and has been preliminarily validated by plasmid transfection in CHO cell line. With iGEM database in mind, the kit follows a modular design and aims to facilitate future iGEM projects with greater flexibility and compatibility in gene editing.", "Our gene editing kit has three components: Guide RNA (g-RNA), outer membrane protein of TMV homologous DNA sequences and CRISPR-Cas9 enzyme. Both the g-RNA and the homologous DNA sequences have high specificity in CHO. And the CRISPR-Cas9 enzyme was proven to be efficient in eukaryotic cells.", "It is the record of our experiments, which concludes every step of design, build-up, and examine; it is the trace of our life, which leaves us the most valuable memory of fighting, sharing, and devoting; it is the path in springtime, which not only gives us a chance to learn synthetic biology, but also provides a platform to boarder our views.", "1.Would any of your project ideas raise safety issues in terms of: researcher safety, public safety, or environmental safety? 2.Do any of the new BioBrick parts (or devices) that you made this year raise safety issues? 3.Is there a local biosafety group, committee, or review board at your institution?4. Do you have any other ideas how to deal with safety issues that could be useful for future iGEM competitions? How could parts, devices and systems be made even safer through biosafety engineering?", "To attract more attention on the competition and our project about the CRISPR-Cas system, we ran a club named iGEMER at NFLS. A home page about our study has been created since we started our project. On the website, we have several segments: team introduction, project progress, notebook, results and conclusions, safety, attributions, human practices and amusement. ", "We are a group of passionate syudents from Nanjing Foreign Languages School, specializing in different disciplines: BIO, computer science, mathematics.., we gather together, questing for the same interest.

A
gRNA Specific Recognition Sequence Transcription Vectors

There are three sets of gRNA.
The Guide-RNA sequence comes from Addgene plasmid 41824(gRNA_Cloning Vector).
The Guide-RNA sequence is inserted in the DNA from into basic plasmid backbone pSB1C3(BBa_J04450)with BioBrick cloning site prefix(EcoR I,Xba I)and suffix(Spe I,Pst I). When the plasmid is transfected into the mammalian cell nuclei, the plasmid will transcript into the form of Guide-RNA or gRNA.

CRISPR-Cas9 Enzyme

Microbes rely on diverse defense mechanisms that allow them to withstand viral predation and exposure to invading nucleic acid. In many Bacteria and most Archaea, clustered regularly interspaced short palindromic repeats (CRISPR) form peculiar genetic loci, which provide acquired immunity against viruses and plasmids by targeting nucleic acid in a sequence-specific manner. These hypervariable loci take up genetic material from invasive elements and build up inheritable DNA-encoded immunity over time. Conversely, viruses have devised mutational escape strategies that allow them to circumvent the CRISPR/Cas system, albeit at a cost. CRISPR features may be exploited for typing purposes, epidemiological studies, host-virus ecological surveys, building specific immunity against undesirable genetic elements, and enhancing viral resistance in domesticated microbes.
