Catalog Number: 1933
Alternate Names: Exenatide, AC 2993
Biological Activity
High affinity glucagon-like peptide 1 (GLP-1) receptor agonist (Kd = 136 pM); originally isolated from Heloderma suspectum venom. Potently induces cAMP formation without stimulating amylase release in pancreatic acini. Potentiates glucose-induced insulin secretion in isolated rat islets. Protects against glutamate-induced neurotoxicity.

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?
