Biological Activity

RepSox is a potent and selective inhibitor of the TGF-β type I receptor/ALK5 (IC50 values are 4 and 23 nM for TGF-β type I receptor autophosphorylation and binding respectively). RepSox is selective for TGF-β type I receptor over a range of kinases, including p38 MAPK, JNK1 and GSK3 (IC50 > 16 μM). Enhances the efficiency of cellular reprogramming; replaces Sox2 by inducing Nanog expression.

RepSox synthesized to Ancillary Material Grade also available.

For more information about how RepSox may be used, see our protocols: Highly Efficient Generation of CiPSCs from MEFs, Generation of β cells from hPSCs, Reprogramming MEFs into Skeletal Muscle Progenitors.
