Catalog Number: 2471
Chemical Name: 10-(3-Aminopropyl)-3,4-dimethyl-9(10H)-acridinone maleate
Biological Activity
Selective inhibitor of Syk kinase. Inhibits tyrosine phosphorylation of Syk initiated by the engagement of FcεRI in rat and human mast cells. Results in the abrogation of degranulation, TNF-α production (IC50 = 10 μM) and other related signaling events.

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?
