Catalog Number: 5941
Biological Activity
Potent rat Nav1.7, human Nav1.4 and rat Nav1.6 channel activator (EC50 values are 7, 10 and 47 nM, respectively). Exhibits minimal activation at mammalian Nav1.2, Nav1.3 and Nav1.5 (EC50 values >3 μM). Inhibits fast inactivation on all channels. Increases peak currents at all voltages and stimulates a persistent Na+ current at hNav1.7 channel. Increases hyperpolarization at Nav1.4 and Nav1.6 channels. Induces spontaneous pain 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?
