Catalog Number: 5498
Biological Activity
High affinity, selective ANP clearance receptor (NPR3) antagonist (Ki = 0.45 nM). Exhibits >20,000-fold selectivity for NPR3 over NPR1. Inhibits ANP-stimulated Na+/K+ pump activity in rabbit ventricular cardiomyocytes in vitro. Also blocks proliferation of rodent neonatal cardiomyocytes seen at low ANP concentrations in vitro.

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?
