Catalog Number: 1264
Chemical Name: 4-[4-(4-Fluorophenyl)-5-(4-pyridinyl)-1H-imidazol-2-yl]phenol
Biological Activity
A highly selective, potent and cell-permeable inhibitor of p38 MAP kinase. Binds within the ATP pocket of the active kinase (Kd = 38 nM, as measured in recombinant human p38), and selectively inhibits the p38α and β isoforms (IC50 = 50 and 100 nM at SAPK2a/p38 and SAPK2b/p38β2 respectively). Promotes stability of naive human pluripotent stem cells in culture. Also available as part of the MAPK Inhibitor Tocriset™.

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?
