Cellecta offers Cas9 nuclease constructs for CRISPR Knockout and CRISPRa/i systems.
For targeted gene knockouts and screening using CRISPR, Cellecta offers lentiviral plasmids that express S. pyogenes Cas9 nuclease.
The constructs are available in both packaged and plasmid forms.
For use with the CRISPR gene inhibition (CRISPRi) or gene activation (CRISPRa) systems, plasmid expressing both dCas9-KRAB and dCas9-VPH are available.
We can also provide other configurations of Cas9 plasmid on a custom basis, please inquire if you need something different than the items described above.
