Cas9 Stable Cell Lines

CRISPR/Cas9 system used for genome engineering in molecular biology is composed of two components: sgRNA which is a combine of original trRNA and crRNA, and Cas9 endonuclease. By delivering Cas9 and sgRNA into a cell, Cas9 is targeted to a given locus based on sequence complementary between sgRNA and cell genome, and further induces a double strand break (DSB).
