Cas9 (7A9-3A3) Mouse mAb (Biotinylated) recognizes transfected levels of total Cas9 protein.Monoclonal antibody is produced by immunizing animals with recombinant protein specific to the amino terminus of Cas9 from Streptococcus pyogene.This Cell Signaling Technology antibody is conjugated to biotin under optimal conditions. The biotinylated antibody is expected to exhibit the same species cross-reactivity as the unconjugated Cas9 (7A9-3A3) Mouse mAb #14697.
