How do you dissolve Y-27632?
Y-27632 (hydrochloride) is soluble in organic solvents such as ethanol, DMSO, and dimethyl formamide. The solubility of Y-27632 (hydrochloride) in these solvents is approximately 5, 30, and 20 mg/ml, respectively.
How do you reconstitute ROCK inhibitors?
For most hESC applications, reconstitute Y-27632 (Molar mass: 338.3) to 1 mM stock concentration in sterile distilled water. Aliquot and store at -20°C for up to one year. Aliquots can be thawed and diluted to a working concentration of 10 μM for hESC applications.
How does Y-27632 inhibit ROCK?
Y-27632 is a cell-permeable, highly potent and selective inhibitor of Rho-associated, coiled-coil containing protein kinase (ROCK). Y-27632 inhibits both ROCK1 (Ki = 220 nM) and ROCK2 (Ki = 300 nM) by competing with ATP for binding to the catalytic site (Davies et al.; Ishizaki et al.).
What does ROCK inhibitor do?
A ROCK inhibitor permits survival of dissociated human embryonic stem cells.
What does Rho kinase do?
Rho-associated kinase (Rho-kinase/ROCK/ROK) is an effector of the small GTPase Rho and belongs to the AGC family of kinases. Rho-kinase has pleiotropic functions including the regulation of cellular contraction, motility, morphology, polarity, cell division, and gene expression.
How do you defrost a ROCK inhibitor?
Thaw at 4 °C overnight. Store aliquots at −20 °C, and thaw directly before use only at room temperature (25 °C).
What is Rho ROCK pathway?
The Rho/Rho-associated coiled-coil containing protein kinase (Rho/ROCK) signaling pathway is an important signal transduction system within the central nervous system, and is critically involved in cell growth, differentiation, migration and development (Chen et al., 2013).
What is the Rho kinase pathway?
The Rho-Rho-kinase pathway modulates the level of phosphorylation of the myosin light chain of myosin II, mainly through inhibition of myosin phosphatase, and contributes to agonist-induced Ca2+ sensitization in smooth muscle contraction.
How do I make E8 media?
Essential 8™ (TeSR™-E8) Media Add 10 mL of E8 supplement (50x) to the 490 mL of basal cold (2-8 °C) medium. Aliquot medium into volumes required for 1 week of culture work. Complete E8 may be stored at 2-8 °C for 1 week or at -20 °C for 6 months. Frozen complete E8 may be thawed once.
How do you unfreeze iPS cells?
Thawing Human iPS cells Remove iPSC from liquid nitrogen vapor or dry ice and immerse the cryovial in a 37°C water bath. Thaw quickly by gently swirling until only a small piece of frozen material remains. Spray the vial with 70% ethanol before transferring to a biological safety cabinet.
What does Rho-kinase do?
Is Rho-kinase an enzyme?
Rho-associated protein kinase (ROCK) is a kinase belonging to the AGC (PKA/ PKG/PKC) family of serine-threonine kinases. It is involved mainly in regulating the shape and movement of cells by acting on the cytoskeleton….Rho-associated protein kinase.

What is the ROCK inhibitor (Y-27632)?
The ROCK Inhibitor (Y-27632) is available in a 5 mg format & has been optimized & validated for cell culture & Neuroscience applications. – Find MSDS or SDS, a COA, data sheets and more information.
How to prepare ROCK inhibitor Y-27632 in cell culture media?
Dilute 10 mM ROCK Inhibitor Y-27632 1:1000 in cell culture medium to obtain a final concentration of 10 μM. For example, if you are preparing 500 mL of media add 0.5 ml 10 mM ROCK inhibitor Medium supplemented with ROCK Inhibitor Y-27632 must be used immediately. Handling Procedure for Frozen Cells and Initiation of Cultures
What is Rho-associated protein kinase inhibitor Y-27632?
ROCK Inhibitor (Y-27632) is a selective, ATP-competitive inhibitor of Rho-associated protein kinase (ROCK) including p160Rock (Ki=140nM) and Rock-II. Also acts as a potent inhibitor of agonist-induced Ca2+ sensitization of myosin phosphorylation and smooth muscle contraction.
How does Y-27632 work?
Y-27632 is a cell-permeable, highly potent and selective inhibitor of Rho-associated, coiled-coil containing protein kinase (ROCK). Y-27632 inhibits both ROCK1 (Ki = 220 nM) and ROCK2 (Ki = 300 nM) by competing with ATP for binding to the catalytic site.
