Catalog Number: 0903
Chemical Name: (2S,4R)-4-Methylglutamic acid
Biological Activity
Potent and highly selective kainate receptor agonist, with an IC50 for inhibition of [3H]-kainate binding of 35 nM and almost 3,000- and 200-fold selectivity for kainate receptors over AMPA and NMDA receptors respectively. Also selectively inhibits the cloned excitatory amino acid transporter EAAT2 at higher concentrations. Also available as part of the Excitatory Amino Acid Transporter Inhibitor Tocriset™ and Kainate Receptor Tocriset™.

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?
