Catalog Number: 2711
Biological Activity
Selective VPAC2 receptor agonist (EC50 values are 0.4, 100 and >1000 nM for VPAC2, VPAC1 and PAC1, respectively in a cAMP accumulation assay; IC50 values are 60, 8700 and >10000 nM for VPAC2, VPAC1 and PAC1, respectively in a competition binding assay). Stimulates glucose-dependent insulin secretion in isolated human pancreatic islets. Reduces HIV-1 viral replication and shows cooperative effects when given in conjunction with VPAC1 agonists.

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?
