CRISPR/Cas9 Knock-out Cell Line Services

Integrating exogenous plasmid DNA into the chromosome of host cells, and then expressing the target protein for a long time is called a stable cell line. A high-quality stable cell line plays an essential role in biological research, including biosimilar development, gene function research and recombinant antibody production. However, constructing an effective cell line is a complex and time-consuming task. KMD Bioscience is experienced in stable cell line construction. Combining advanced instrumentation and skilled scientists, KMD Bioscience can provide you with a high-quality cell line construction service. Cell lines constructed by KMD Bioscience can be directly applied to downstream biological research. We have successfully constructed a large number of target cell lines for many research clients. Based on advanced technology and dedicated research teams, KMD Bioscience can provide the following services:

CRISPR/Cas9 Knock-out Cell Line Construction:


CRISPR/Cas9 is a powerful technique for genome manipulation and causing a buzz in the science world. It has the potential to alter the course of research and drug discovery by providing scientists with a powerful tool to change any gene in any cell in a highly targeted manner and without introducing foreign DNA. In the Type II CRISPR System (Fig 1), CRISPR RNA (crRNA) and trans-activating crRNA (tracrRNA) form a complex through base pairing that can specifically recognize genomic sequences. Then the PAM (5'-NGG-3') sequence binds and invades DNA, directing the Cas9 endonuclease to generate double-strand breaks (DSBs) in the target fragment. This complex can be simplified by fusing crRNA and tracrRNA sequences to form single-guided RNA (sgRNA). The fused RNA has similar activity to wild-type and is more convenient for researchers because of its simplified structure. By connecting the elements of sgRNA and Cas9, it is possible to obtain a plasmid that can express both of them simultaneously. It can then be transfected into cells to manipulate the target gene.
