      ROCK Inhibitor (Y-27632)

      BD™ ROCK Inhibitor (Y-27632)

      (RUO)
      ROCK Inhibitor (Y-27632)
      ROCK inhibitor, Y-27632, improves the recovery of human embryonic stem cells (hESC) after fluorescence activated cell sorting. H9 hESC (WiCell, Madison, WI) were grown in mTESR™1 medium (StemCell Technologies) on BD Matrigel™ hESC-qualified Matrix (Cat. No. 354277), dissociated with BD™ Accutase™ Cell Detachment Solution (Cat. No. 561527), and sorted on a BD FACSAria™ II cell sorter based upon cell-surface expression of SSEA-3, TRA-1-81 and SSEA-1 using the BD Stemflow™ Human Pluripotent Stem Cell Sorting and Analysis Kit, (Cat. No. 560461). ROCK Inhibitor was either omitted or added for 24 hours post-sort. Bright-field images of the hESC at days 1 and 3 after sorting and culturing without or with ROCK Inhibitor are shown. Day 1, no treatment (Top left panel). Day 3, no treatment (Top right panel). Day 1, 10 µM Y-27632 treatment (Bottom left panel). Day 3, 10 µM Y-27632 treatment (Bottom right panel). For details please see Emre et al., 2010.

      Recommended Assay Procedures

      For a working solution, dilute to 10 mM in sterile deionized water. [The molar mass of Y-27632 is 338.3 g/mol.]

      Small aliquots may be stored at -20°C, avoiding repeated freeze-thaw cycles.

      Use at 10 µM in culture medium. Since applications vary, each investigator should titrate the reagent to obtain optimal results.

      Antibody Details
      Down Arrow Up Arrow

      The ROCK inhibitor, Y-27632, is a selective inhibitor of the p160-Rho-associated coiled kinase (ROCK) and is a factor that enhances embryonic stem cell survival upon single cell dissociation. In addition to increasing cell recovery after dissociation, Y-27632 has been used for various other applications in stem cell research including cryopreservation, sorting, reprogramming, transplantation, and differentiation.
