Description: Highly selective GSK-3 inhibitor
Chemical Name: 6-[[2-[[4-(2,4-Dichlorophenyl)-5-(5-methyl-1H-imidazol-2-yl)-2-pyrimidinyl]amino]ethyl]amino]-3-pyridinecarbonitrile
Purity: ≥98% (HPLC)
Biological Activity
Potent and highly selective inhibitor of glycogen synthase kinase 3 (GSK-3) (IC50 values are 6.7 and 10 nM for GSK-3β and GSK-3α respectively). Exhibits >500-fold selectivity for GSK-3 over closely related kinases; also displays >800-fold selectivity against 45 additional enzymes and receptors. In combination with tranylcypromine (Cat. No. 3852), enables reprogramming of mouse embryonic fibroblasts, transduced by Oct4 and Klf4 only, into iPSCs. Enhances mouse and human ESC self-renewal when used in combination with PD 0325901 (Cat. No. 4192). Allows formation of extended pluripotent stem (EPS) cells in combination with (S)-(+)-Dimethindene maleate (Cat.No. 1425), minocycline hydrochloride (Cat.No. 3268) and human leukemia inhibitory factor.

Cell Line/Tissue: pluripotent stem cells
For directed differentiation of pluripotent stem cells to kidney organoids, cells are treated with GSK-3 inhibitor, CHIR99021 to induce canonical WNT signaling. CHIR99021 concentration and differentiation time period are the key factors for this protocol. I found this product gave me reproducible results.
Although the datasheet says store at -20°C, it's better to aliquot and keep it at -80°C for long term storage.
