Catalog Number: 3420
Biological Activity
Potent melanocortin MC3 and MC4 receptor antagonist (IC50 values are 0.23 and 0.06 nM respectively) and MC5 partial agonist (EC50 = 0.12 nM). Upregulates expression of genes promoting lipogenesis and triglyceride storage (SCD1, LPL, ACCα and FAS), increases triglyceride synthesis and promotes insulin resistance. Increases food intake, body weight and fat mass when administered centrally 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?
