Chemical Name: 1-Ethyl-2-benzimidazolinone

Biological Activity

Activator of epithelial KCa channels, stimulates a large and sustained trans-epithelial Cl- secretory response across T84 monolayers. Induces hyperpolarization to the same magnitude as ACh in aortic value endothelial cells. Promotes embryonic stem cell (ESC) differentiation into cardiomyocytes.

Technical Data

Soluble to 100 mM in ethanol and to 100 mM in DMSO
>99 %
Store at RT
