Biological Activity for CHIR 99021

CHIR 99021 is a 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). Acts as Wnt activator. 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 the irreversible inhibitor of LSD1 (Cat. No. 3852), CHIR 99021 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). It promotes differentiation of hPSCs in cardiomyocytes and allows formation of extended pluripotent stem (EPS) cells in combination with (S)-(+)-Dimethindene maleate (Cat.No. 1425), tetracycline antibiotic (Cat.No. 3268) and human leukemia inhibitory factor.

CHIR 99021 synthesized to cGMP guidelines also available.

Differentiation of human pluripotent stem cells.
By Paul Humphreys on 11/20/2020
Assay Type: In Vitro
Species: Human
Cell Line/Tissue: hPSCs

Directed differentiation of human pluripotent stem cells (hPSCs) towards mesoderm lineages. Used at concentration of 3uM. Very effective in induction of mesoderm markers.

Perform titration against your cell line to optimise correct concentration.

For maintenance of stem cells pluripotency.
By Anonymous on 06/25/2020
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: Neural Stem Cells

For directed differentiation to neural, cells are treated with GSK-3 inhibitor, CHIR99021 to induce canonical WNT signaling. This product gave me reproducible results.

It's better to aliquot and keep it at -80°C for long term storage.

Check the maintenance of naive pluripotency in 2i.
By Megha PB on 07/18/2018
Assay Type: In Vitro
Species: Mouse
Cell Line/Tissue: E14TG2a

Culture mouse ES cells in 2i media and without 2i to assess differentiation. Only the cells in 2i are pluripotent while mES cells cultured in -2i for 48 hours exit naive pluripotency.

reliable product.
By Pinyuan Tian on 07/05/2018
Assay Type: In Vitro
Species: Human
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.

Pathways for CHIR 99021

Wnt Signaling Pathway

Wnt Signaling Pathway

The Wnt pathway is involved in cellular differentiation and proliferation in adult tissues and also during embryogenesis. Disturbances within the pathway may lead to the formation of tumors and promote metastasis.
