Catalog Number: 2529
Biological Activity
Urotensin-II (UT) receptor ligand; behaves as a silent antagonist in most in vitro assays and in vivo, but does retain small residual agonist activity under certain conditions in some assays. Competitively antagonizes U-II induced contractions in the rat aorta (pIC50 = 7.46) and prevents plasma extravasation elicited by U-II in mice in vivo.

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?
