The CRISPR Integration Kit provides the essential genome editing reagents necessary to integrate a BstNI restriction site to the human KRAS locus. This kit is intended to serve as a tool to evaluate cell lines for ability to integrate new sequences at CRISPR-effected double strand breaks with the aid of short oligonucleotide donor. Integration efficiencies obtained with this kit enable rational design of genome editing experiments in a wide range of cell lines.
CRISPR/Cas9 can be used to introduce, or “knock in”, new DNA sequences. Common modifications include the introduction of a SNP, small tag, loxP or larger cassette such as fluorescent protein. These modifications are made through the introduction of targeted DSB which enhance targeted integration significantly (Choulika et al., 1995). Targeted integration (gene knock in) occurs through homology directed repair (HDR)( (Bibikova et al., 2002). In order to enable gene editing by HDR, a DNA ‘donor′ or repair template containing the desired sequence must be delivered to the cell along with gRNA and Cas9.
