    Product Description

    RS-1 is an activator of DNA repair protein RAD51 (Kd = 48-107 for human RAD51 with different cofactors present).1 It stimulates homologous strand assimilation activity at least 5- to 11-old, enhancing homologous recombination activity of hRAD51.1 RS-1 is a potent enhancer of CRISPR-mediated genome editing, increasing homology directed repair 3- to 6-fold.2 It is used to increase CRISPR-mediated knock-in efficiencies in vitro and in vivo.2,3,4

    WARNING This product is not for human or veterinary use.
