Catalog Number: 1420
Biological Activity
Phosphorylation product of inositol 1,4,5-trisphosphate (Ins (1,4,5)P3). Potent inhibitor of Ins (1,4,5)P3 5-phosphatase (IC50 ~150 nM); facilitates Ca2+ influx by sensitizing Ins (1,4,5)P3-mediated activation of ICRAC. At higher concentrations, acts as an inhibitor of Ins (1,4,5)P3�receptors.

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?
