Catalog Number: 5462
Chemical Name: N,N,N-Triethyl-2-oxo-2-[[4-[2-[4-[(1-oxo-2-propen-1-yl)amino]phenyl]diazenyl]phenylamino]ethanaminium chloride
Biological Activity
Photoswitchable Kv channel blocker (IC50 values are 2 and 64 μM at 500 nm and 380 nm respectively). Switches conformation from cis to trans at 500 nm and trans to cis at 380 nm. Exhibits minimal activity at Nav1.2 and L-type Ca2+ channels. Stimulates action potential firing of hippocampal neurons in vitro at 500 nm and restores visual responsiveness in blind mice at 380 nm.

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?
