To prevent human ES/ iPS cell death

Y-27632, MF

Y-27632, MF was registered in the Drug Master File (MF) in Japan as additives for culture medium in September 2015. We ensure high stability and quality of the products by validating the manufacturing and analytical processes and implementing change control strategies.

GMP products comming soon!

FUJIFILM Wako will provide the small molecules produced through GMP based on ICHQ7 in 2021.


What is Y-27632?

Selective and potent ROCK inhibitor


Y-27632 plays various roles including contraction of vascular smooth muscle cells via ROCK signaling pathways. Furthermore, it suppresses the cell death of ES/iPS cells at cell dispersion, and that it improves cell survival after cryopreservation.
