Biological Activity for Compound E
Compound E is a γ-secretase and notch patchway inhibitor. Compound E enhances growth inhibition, differentiation and migration of neuroblastoma cells when used in a combination with DAPT (Cat. No. 2634) and 13-cis RA. In combination with hLIF, CHIR 99021 (Cat. No. 4423) and SB 431542 (Cat. No. 1614), Compound E accelerates the induction of a homogeneous, self-renewing primitive neuroepithelium population from hESCs. Compound E is active in vitro and in vivo.
For more information about how Compound E may be used, see our protocol: Generation of β cells from hPSCs
