Catalog Number: 4911
Alternate Names: Leiuropeptide II
Biological Activity
Very high affinity ClC-2 blocker (apparent KD ~ 50 pM). Slows ClC-2 activation and inhibits slow-gating but does not inhibit open ClC-2 channels. Selective for ClC-2 over other ClC family members (ClC-0, ClC-1, ClC-3 and ClC-4), CFTR, GABAC, CaCC and KV1.2.

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?
