Catalog Number: 3905
Alternate Names: NAADP
Chemical Name: Nicotinic acid adenine dinucleotide phosphate tetrasodium salt
Biological Activity
Ca2+ mobilizing agent. Initiates Ca2+ release via type 1 ryanodine receptor (RyR1) activation. Also regulates Ca2+ release from intracellular stores distinct from the endoplasmic reticulum (ER); displays affinity for two-pore channels (TPCs) which release Ca2+ from acidic organelles.

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?
