Catalog Number: 2265
Biological Activity
Cell-permeable inhibitor of Lyn-dependent effects of the IL-5 receptor. Blocks binding of Lyn tyrosine kinase to βc subunit of IL-3/GM-CSF/IL-5 receptors, blocking Lyn activation. Inhibits IL-5 receptor-mediated eosinophil differentiation and survival in vitro. Inhibits airway eosinophilic inflammation in mouse model of asthma.

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?
