|Description||PF-431396 is a dual PYK2/FAK inhibitor with IC50 of 11 nM and 2 nM, respectively.|
In A20 cells, PF-431396 blocks anti-Ig- and clustering LFA-1-induced tyrosine phosphorylation of Pyk2 and FAK, and further blocks B cell spreading.  PF-431396 consistently inhibits the increase in protein tyrosine phosphorylation (PY) induced by the absence of added calcium and induced by W-7 in the presence of calcium. 
|In vitro||DMSO||100 mg/mL (197.43 mM)|
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
