Stemolecule™ Y27632

Y27632 is a cell-permeable small molecule Rho-associated kinase (ROCK) inhibitor¹. Y27632 has been found to prevent apoptosis as well as enhance the survival and cloning efficiency of dissociated human embryonic stem (ES) cells without affecting their self-renewal properties or pluripotency². This molecule has also been shown to enhance survival during the transplantation of ES cell-derived neural precursors³. Y27632 in combination with Pifithrin-u significantly improves cell recovery after cryopreservation⁴.

Stemolecule Y27632 is also available as a 10 mM DMSO Stock Solution in DMSO (2 mg in 624.4 μl) (Cat. No. 04-0012-02).

Y27632 is widely used in naive stem cell protocols⁵, such as the 5i/L/A/ protocol.
