Catalog Number: 1636
Chemical Name: N,N,H,-Trimethyl-5-[(tricyclo[,7]dec-1-ylmethyl)amino]-1-pentanaminiumbromide hydrobromide
Biological Activity
Voltage-dependent open-channel blocker of AMPA receptors. Selective for GluR2 subunit-lacking (Ca2+-permeable) receptors over GluR2-containing receptors (IC50 values are 2.6 and 1102 μM, respectively). Selectively blocks fast spiking interneuron but not medium spiny projection neuron in mouse striatum. Also blocks NMDA receptor-mediated currents. Anticonvulsant in vivo.

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?
