Data sheet
| Application | GMP grade NLS-cas9-NLS for in vivo and in vitro gene-editing projects. |
More info
| Application | Recombinant Cas9 Protein GMP grade is a recombinant wild-type Streptcoccus pyogenes Cas9 nuclease containing nuclear-localization signal (NLS) at C-terminal expressed and purified from E.coli. The Cas9 protein solution has been verified to be well-tolerated by mammalian cells when electroporated or microinjected as a ribonucleoprotein complex (RNP) with a single guide RNA (sg RNA) for knockout experiments. This product is manufactured according to relevant GMP guidelines. |
