Catalog Number: 4474
Chemical Name: (3β)-Cholest-5-ene-3,20-diol
Biological Activity
Allosteric activator of the Hedgehog signaling pathway Smoothened (Smo) oncoprotein; binds at a site distinct from the canonical cyclopamine binding site. Activates Hedgehog (Hh) signaling (EC50 ~ 3μM for induction of Hh reporter gene transcription in in NIH 3T3 cells). Induces Smo accumulation in primary cilia; also exhibits osteogenic activity and activates the liver X receptor (LXR).

Molarity Calculator
Calculate the mass, volume or concentration required for a solution

The molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) x Volume (L) x Molecular Weight (g/mol)
An example of a molarity calculation using the molarity calculator:
What is the mass of compound required to make a 10 mM stock solution in 10 ml of water given that the molecular weight of the compound is 197.13 g/mol?
