CHIR99021 is the most selective inhibitor of glycogen synthase kinase 3β (GSK3β). CHIR99021 does not show cross-reactivity against cyclin-dependent kinases (CDKs) with a 350 fold selectivity toward GSK3β compared to CDKs with a Kᵢ of <10nM in vitro. CHIR99021 has been shown in long term expansion of murine embryonic stem cells in conjunction with MEK/MAPK inhibitor PD184352 and fibroblast growth factor receptor (FGFR) inhibitor SU5402.

PRODUCT USE

Soluble in DMSO (100mM). For a 10 mM solution, reconstitute by adding 430µl of DMSO to the entire contents of the vial. For most cells, the maximum tolerance to DMSO is <0.5%. Incubate in a 37°C water bath for 5 minutes if a precipitate is observed.

When used in combination with PD0325901, CHIR99021 has been shown to sustain ES cell self-renewal.
