Catalog Number: 1650
Alternate Names: Bovine adrenal medullary peptide-22P, BAM 22 (1-22)
Biological Activity
Potent endogenous agonist peptide for the newly identified sensory neuron specific receptor (SNSR); isolated from bovine adrenal medulla. EC50 values are 13 and 16 nM for human SNSR3 and SNSR4 respectively. Also potent opioid agonist (IC50 = 1.3 nM in guinea pig ileum preparation). Produces opioid- and non-opioid receptor mediated antinociceptive effects 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?
