Cat. No. 1041
Chemical Name: 1-Ethyl-2-benzimidazolinone
Biological ActivityActivator 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.
