CHIR 99021 trihydrochloride


Product overview

  • Name
    CHIR 99021 trihydrochloride
  • Short description
    Potent, selective GSK3 inhibitor. Wnt signaling activator. Water soluble.
  • Biological description

    Potent, selective and ATP-competitive GSK3 β inhibitor (IC50 values are 6.7 and 10 nM for GSK-3β and GSK-3α respectively).

    Water soluble hydrochloride salt of CHIR 99021.

    Wnt signaling activator which is commonly used with PD 032501 as part of the 2i condition.

    Exhibits no cross reactivity against CDKs and exhibits >500-fold selectivity for GSK3 over other protein kinases and >800-fold selectivity over 20+ other enzymes and receptors.

    Promotes self-renewal of embryonic stem cells and enables mouse embryonic fibroblast (MEF) reprogramming into iPSCs.
