Catalog Number: 4224
Chemical Name: Tetradecyltrimethylammonium bromide
Biological Activity
Dynamin inhibitor; inhibits the GTPase activity of dynamin I (Ki = 940 nM; IC50 = 3.1 μM). Targets the dynamin-phospholipid interaction. Inhibits receptor-mediated endocytosis of epidermal growth factor (EGF) in non-neuronal cells; also inhibits synaptic vesicle endocytosis. Displays dynamin I-inhibitory activity similar to OctMAB (Cat. No. 4225).

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?
