Catalog Number: 2071
Alternate Names: [D-Phe11,His12]-Sauvagine (11-40)
Biological Activity
Potent, selective and competitive corticotropin-releasing factor CRF2 receptor antagonist (Kd values are 1.4 and 153.6 nM for binding to mouse CRF2β and rat CRF1 receptors respectively). Inhibits sauvagine-stimulated cAMP accumulation in HEK-mCRF2β cells (pA2 = 8.49). Prevents stress-enhanced fear conditioning and MEK 1/2-dependent activation of ERK1/2 in mice in vivo.

Calculators

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)

As an example, if the molecular weight of a compound is 197.13 g/mol and the desired concentration is 10 mM for 10 ml of water based stock solution, the required mass would be = 19.713 (value determined by this calculator).
