Stable Cell lines - Genome Editing Cell Lines Generation Service
The clustered regularly interspaced short palindromic repeats (CRISPR)/Cas system, which is an important component of bacterial adaptive immunity, consists of the Cas nuclease and two individual RNA components, a programmable crRNA (CRISPR RNA) and a fixed tracrRNA (trans-activating crRNA). Cas protein can cut the invading phage DNA into small fragments, which are then integrated into the CRISPR array as a spacer. Subsequently, the CRISPR array is transcribed to generate crRNA and a complementary tracrRNA, which form a double-stranded RNA structure that recruits Cas proteins for cleavage. Adjacent to the crRNA-targeted sequence on the invading DNA, a short sequence named the protospacer adjacent motif (PAM) plays an essential role in the adaptation and interference stages, which the CRISPR/Cas complex recognizes during target DNA binding. The absence of a PAM sequence can alter the affinity between the Cas9 protein and the target DNA, since a specific PAM sequence serves to recognize target sequences and discriminate others from non-target sequences.
CRISPR/Cas9 system, one of the CRISPR/Cas systems, requires only one cas9 protein, which functions in both RNA-guided DNA recognition relying on sgRNA (single guide RNA) formed by crRNA and tracrRNA fusion and cleavage, making this system potentially useful for genome engineering applications. Alpha Lifetech Inc. uses a modified CRISPR/Cas9 system, where modification of Cas9 protein based on its functional domains, to serve each project with individual genome-editing requirements and provide relative stable cell lines in a short turnaround time. The modified Cas9 protein can generate a double-strand break (DSB) at the targeted region, and then activate the DNA repair mechanism to induce insertions or deletions of the gene of interest.
