Catalog Number: 2689
Alternate Names: Sodium polyoxotungstate
Chemical Name: Sodium metatungstate
Biological Activity
Inhibitor of Ecto-NTPDases that displays minor selectivity for NTPDases 1 and 2 over NTPDase 3 and P2Y12 (Ki values are 2.58, 3.26, > 10 and 28.8 μM for NTPDase 1, NTPDase 3, P2Y12 and NTPDase 2 respectively). Abolishes renal protection induced by ischemic preconditioning. Inhibits synaptic transmission at hippocampal CA1 pyramidal synapses and at the cerebellar parallel fiber-Purkinje cell (PF) synapse.

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?
