| A cell-permeable bis-indolo (indirubin) compound that acts as a highly potent, selective, reversible, and ATP-competitive inhibitor of GSK-3a/b (IC50=5nM). Its specificity has been tested against various Cdks (IC50=83, 300, 320, and 10,000nM for Cdk5/p25, Cdk2/A, Cdk1/B, and Cdk4/D1, respectively) as well as many other commonly studied kinases (IC5010uM), including MAP kinases, PKA, PKC isoforms, PKG, CK, and IRTK. Inhibition of GSK by BIO has been shown to result in the activation of Wnt-signaling pathway and sustained pluripotency in human and murine ESCs (embryonic stem cells). Reported to maintain self-renewal in human and mouse embryonic stem cells. Also induces the differentiation of neonatal cardiomyocytes. CAS Number: 667463-62-9 Formula: C16H10BrN3O2 Primary Target: GSK-3a/b Primary Target IC50: 5nM Secondary Target: IC50 = 83, 300, 320, and 10,000nM for Cdk5/p25, Cdk2/A, Cdk1/B, and Cdk4/D1, respectively. Solubility: DMSO Molecular Weight: 356.2 Storage and Stability: May be stored at 4C. For long-term storage, aliquot and store at 4C. Do not freeze. For maximum recovery of product, centrifuge the original vial prior to removing the cap. Further dilutions can be made in assay buffer. |
