Catalog Number: 5376
Chemical Name: (3β)-3-(Sulfooxy)-pregn-5-en-20-one sodium salt
Biological Activity
Highly potent neurosteroid; enhances intracellular Ca2+ upon NMDA receptor-mediated synaptic activity (EC50 = ~2 pM) and potentiates NMDA responses. Activates CREB phosphorylation, augments LTP and cognitive behavior in rat memory models. Also activates TRPM3 channels.

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?
