• Hintergrund

  • Hintergrund

    The enhanced specificity Cas9 protein from Streptococcus pyogenes (~160 KD), modified at sites K848A/K1003A/R1060A, exhibit substantially reduced off-target cleavage in cells. When combined with target RNAs, eSpCas9 protein will act as a targeted nuclease suitable for transfection of cell cultures and help the development of genetically-modified animals via one-cell embryo injection.
