|Description||Cas9 Nuclease NLS, S. pyogenes, is an RNA-guided endonuclease that catalyzes site-specific cleavage of double stranded DNA. The location of the break is within the target sequence 3 bases from the NGG PAM (Protospacer Adjacent Motif). The design of single guide RNA (sgRNA) is dependent on the target region close to the PAM site. Even if you pick a target sequence that fulfills all of the described requirements, sgRNA specificity and activity is unpredictable. Therefore, it is often recommended that multiple, different sgRNAs be designed to target a gene of interest. The GenCrispr sgRNA Screening Kit provides a simple, reliable, and rapid method for assessing sgRNA efficiency before cell transduction, allowing you to identify the highly effective CRISPR sgRNA.
|Storage||Store at -20°C upon receipt. positive control sgRNA should be aliquoted and stored at -80°C, to avoid repeated freeze/thaw cycles.|
|Evaluate the efficiency of sgRNAs for CRISPR/Cas9 in vitro> studies and identify the highly effective sgRNAs before cell transfection.
gRNA efficiency screening using GenCRISPR sgRNA screening kit.
Twelve unique synthesized gRNAs were incubated with Cas9 nuclease for 1 h at 37°C according to the instructions in theGenCRISPR sgRNA screening kit manual. Upon separating the reactions by agarose gel electrophoresis, only gRNA9 was observed to induce cleavage.
