Catalog Number: 1443
Alternate Names: Kisspeptin-54, Kp-54
Biological Activity
Potent endogenous ligand of the kisspeptin receptor (KISS1, GPR54). Binds with high affinity to rat and human KISS1 receptors with Ki values of 1.80 and 1.45 nM respectively. Inhibits chemotaxis, invasion and metastasis of human melanomas and breast carcinomas. Stimulates gonadotropin secretion following i.c.v. administration.

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?
