CleanCap® Cas9 Nickase mRNA (5moU)

CleanCap^® CRISPR Associated Nickase Protein mRNA (5-methoxyuridine)

Cas9 Nickase mRNA expresses a version of the Streptococcus pyogenes SF370 Cas9 protein (CRISPR Associated Protein 9) that contains a D10A amino acid substitution. This mRNA also contains a C-terminal nuclear localization signal followed by a HA tag.

Cas9 functions as part of the CRISPR (clustered regularly interspaced short palindromic repeats) genome editing system. In the CRISPR system, an RNA guide sequence targets the site of interest and the Cas9 protein is employed to perform the DNA cleavage. While wild-type Cas9 creates a double stranded break at the target site, Cas9 nickase creates a single stranded break. This favors homology-directed repair and decreases the occurrence of non-homologous end joining.

This mRNA is capped using CleanCap, TriLink's proprietary co-transciptional capping method, which results in the naturally occuring Cap 1 structure with high capping efficiency. It is polyadenylated, modified with 5-methoxyuridine and optimized for mammalian systems. It mimics a fully processed mature mRNA.
