Catalog Number: 1590
Biological Activity
Highly potent and selective NOP receptor agonist (EC50 = 1 nM). Displays > 875-fold selectivity over opioid receptors (IC50 values are 0.32, 280, > 10000 and 1500 for NOP, μ, δ and κ receptors respectively). Longer lasting and 30-fold more potent than nociceptin in vivo; pronociceptive and inhibits locomotor activity.

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?
