Catalog Number: 3390
Biological Activity
Naturally occuring, potent regulator of actin polymerization present in human platelets at a concentration of 200 - 500 μM. Sequesters G-actin monomers in a 1:1 ratio (Kd = 0.7 - 1.0 μM) and allows rapid filament polymerization in the presence of profilin. Implicated in wound healing, induction of MMPs, chemotaxis, angiogenesis, inflammatory processes and tumor progression.

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?
