Catalog Number: 1794
Chemical Name: N-[[(3R)-1-(Aminoiminomethyl)-3-piperidinyl]acetyl]-4-(phenylethynyl)-L-phenylalanine methyl ester trifluoroacetate
Biological Activity
Competitive reversible inhibitor of interleukin-2 (IL-2) binding to its receptor (IC50 = 3 μM for inhibition of IL-2 interaction with IL-2R α-subunit). Appears to compete with IL-2Rα for its binding site on IL-2.

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?
