Description
The GenCRISPR™
Ultra eSpCas9 product line provides customers with a selection of research use,
basic GMP and GMP compliant Cas9 nucleases. The Cas9 protein can be formed with
the guide RNA into a ribonucleoprotien (RNP) complex. The use of an RNP complex
to perform gene editing has been shown to reduce the challenges encountered
with other CRISPR gene editing techniques such as viral and plasmid delivery.
Challenges include off-target effects, cell viability and transcription/translational
challenges.
GenCRISPR™ Ultra eSpCas9-N-NLS
Research, tag-free is a mutant form of Cas9
nuclease and is produced by expression in an E. coli strain carrying a plasmid encoding the eSpCas9 gene from Streptococcus pyogenes with an N-terminal
nuclear localization signal (N-NLS). GenCRISPR™ Ultra eSpCas9-N-NLS Research,
tag-free delivers higher fidelity
and less off-target activity than wild-type SpCas9 nuclease.
