Biological Activity

endo-IWR 1 is an inhibitor of Wnt signaling. Induces an increase in axin2 protein levels; promotes β-catenin phosphorylation by stabilizing Axin-scaffolded destruction complexes. Promotes endothelial cell specification of cardiac progenitor cells and may be used in protocols for the generation of retinal pigment epithelial cells from hPSCs.

Negative Control also available.

endo-IWR 1 synthesized to Ancillary Material Grade also available.

For more information about how endo-IWR 1 may be used, see our protocol: Generation and Propagation of EPS cells (LCDM Cocktail).
