Knockout Stable Cell Lines

The CRISPR/Cas9 system has been developed as the most popular method for genome editing in recent years. The engineered CRISPR/Cas9 technology consists of a single guide RNA (sgRNA) and a human codon optimized Cas9 nuclease. The sgRNA recognizes the genomic target via standard Watson–crick base pairing and acts as a scaffold for binding of the endonuclease Cas9. Then Cas9 protein introduces site-specific DSBs in the target DNA sequences. Besides, in the phase of target recognition, the protospacer adjacent motif (PAM) adjacent to the 3’ end of the DNA target site is indispensable. Finally, targeted mutations can be induced by nonhomologous end joining (NHEJ). CRISPR-Cas9 is a genome-editing tool that is creating a buzz in the science world. It is faster, cheaper and more accurate than previous techniques of editing DNA and has a wide range of potential applications. Our scientists use the CRISPR CAS9 (CRISPR/Cas9) to knock out one or double genes to generate a KO cell line.
