Y27632 (2HCl)

Highly potent inhibitor of p160-Rho-associated coiled protein kinase (ROCK), 10 mg
SKU: SM-0013-0010



Product Description

Y27632 dihydrochloride is a highly specific inhibitor of Rho-associated coiled-coil protein kinase (ROCK) activity as a cell-permeable, ATP-competitive inhibitor of both ROCK1 (Ki of 220 nM) and ROCK2 (Ki 300 nM) (Ishizaki, et al.). Human embryonic stem cell (ESC) survival is improved through enhanced attachment following single cell dissociation and subsequently after FACS analysis or cryopreservation in both feeder-dependent and -independent cultures (Emre, et al.). The enhanced cell attachment and thus recovery is boosted through decreased dissociation-induced apoptosis (Watanabe, et al.).

Product Synonyms:
Y-27632 dihydrochloride, Y-27632, Rock Inhibitor
