Fragment Deleted Stable Cell Line    

CRISPR/Cas9 Platform^CB offers knockout stable cell line generation services for customers, including protein coding gene knockout and deletion of non-coding region (like lncRNA, miRNA). Based on excellent platform and leading-edge technology, our experienced scientist team serves our customers with high-quality products and services.

Since CRISPR/Cas nuclease was first introduced into eukaryotes, it shortly becomes the most widely used tool for genome engineering. Either coding region or non-coding region can be delete by genome-editing tools. CRISPR/Cas9 targets Cas9 nuclease to specific DNA sequence by guide RNA and introduces double strand break. Repair of the DSBs may result in indels, which lead to frame shift of gene and disrupt gene expression at endogenous level. In most cases, frame shift is sufficient to block function of genes. However, a single site of gene editing may be not sufficient to disrupt function when targeting to microRNA or other non-coding region. To overcome this limitation, paired guide RNA targeting both 5’ and 3’ of microRNA are introduced into cells simultaneously for whole region deletion. The large fragment deletion disrupts the structure of miRNA and then results in functional knockout. This strategy also applies to other region of genome, like lncRNA, promoter and enhancer.

CRISPR/Cas9 Platform^CB provides a fragment deletion service for different cell lines, including easy-to-handle cells, tumor cells and stem cells. By using CRISPR/Cas9, we have successfully generated thousands of knockout cell lines (pools or clones), covering from protein-coding genes to non-coding regions. With expert team, we are willing to assist you with your research goals in gene-editing field. Generating custom knockout stable cell line is welcome. We are waiting for your interesting project.
