Catalog Number: 3295
Chemical Name: N-Phthalyl-L-tryptophan
Biological Activity
Non-nucleoside DNA methyltransferase inhibitor that blocks the enzyme active site. Inhibits DNA methylation in human cancer cell lines in vitro without detectable toxicity. Demethylates and reactivates epigenetically silenced tumor suppressor genes. Enhances the efficiency of induced pluripotent stem cell (iPS) generation.

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?
