Cas9 Proteins

A wide range of different recombinant Streptococcus (S.) pyogenes Cas9 proteins are offered by Genaxxon bioscience, all of which are highly pure and effective. Fusion with a nuclear localization signal (NLS) ensures targeting of the Cas9 proteins to the nucleus. Successful genome editing by Eupheria Cas9-NLS proteins has been confirmed in a wide variety of mouse and human cell lines, and organisms, including zebrafish, Xenopus and marine plankton.

Try our Cas9-NLS proteins for your CRISPR/Cas9 experiments for greater genome editing specificity, less cell toxicity and higher insertion/deletion (indel) frequencies than with plasmid- or mRNA-encoded Cas9.

Standard scales are 10, 20, 40 and 100µg.
For pricing and other scales: see below or ask Genaxxon: info@genaxxon.com.

No image available Cas9-Dead-NLS Protein

The Cas9-Dead-NLS protein is catalytically inactive ("dead") due to the D10A and H840A substitutions. Thus Cas9-Dead-NLS binds to DNA, but does not modify it. This property...

No image available Cas9-Dead-NLS-EGFP

This Cas9 protein is catalytically inactive ("dead") due to the D10A and H840A substitutions. The NLS is followed by a C-terminal enhanced green-fluorescence protein (EGFP)...

No image available Cas9-Nickase-NLS

Cas9-Nickases, mutant forms of the Cas9 protein, only cleave the strand complementary to the gRNA, generating a nick in the double-stranded (ds)DNA. Therefore, Cas9-Nickases...
