CleanCap® Cas9 mRNA

CleanCap^® CRISPR Associated Protein 9 mRNA

Cas9 mRNA expresses a version of the Streptococcus pyogenes SF370 Cas9 protein (CRISPR Associated Protein 9). 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 double stranded DNA cleavage.

Cas9 mRNA encodes the Cas9 protein with an N and C terminal nuclear localization signal (NLS). The incorporation of two NLS signals within the mRNA increases the frequency of delivery to the nucleus, thus increasing the rate of DNA cleavage. Additionally, a C terminal HA epitope tag aids detection, isolation, and purification of the Cas9 protein.

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