Catalog Number: 4166
Chemical Name: N-[3,5-Bis(trifluoromethyl)phenyl]-N'-[2,4-dibromo-6-(2H-tetrazol-5-yl)phenyl]urea
Biological Activity
KV4.3 channel activator; mediates the transient outward K+ current (Ito). Increases IKv4.3 peak current amplitude in CHO-K1 cells expressing KV4.3 and KChIP2 (EC50 = 5.3 μM). Inhibits KV1.4-mediated currents independently of KChIP2. Also slows the decay of KV4.2 and KV4.3 currents in the presence of KChIP2.

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?
