Catalog Number: 1439
Chemical Name: Ammoniated ruthenium oxychloride
Biological Activity
Blocks Ca2+ uptake and release from mitochondria, and Ca2+ release from ryanodine-sensitive intracellular stores. Also blocks cell membrane-located capsaicin-activated cation channels (IC50 = 14 nM) and voltage-sensitive Ca2+ channels to inhibit neurotransmitter release.

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?
