Article
Kiran Musunuru’s lab has developed a human codon-optimized Cas9 nuclease from Streptococcus pyogenes, which is optimized for expression in human pluripotent stem cells and co-expresses enhanced green fluorescent protein (EGFP) for cell selection. These plasmids can be used in any human or mammalian cell and can be used in combination with the gRNA vector (Addgene ID 41824) reported in the publication below.
The Cas9 nuclease is based on the version described in:
