Customer Review

Based on 1 Customer Validation

PF-03715455 is a potent inhaled p38 MAPK inhibitor. PF-03715455 shows some selectivity for p38α over p38β with respective IC₅₀ values of 0.88 and 23 nM. PF-03715455 potently inhibits LPS-induced TNFα production in human whole blood (IC₅₀=1.7 nM). PF-03715455 has potential for the treatment of COPD (chronic obstructive pulmonary disease).

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
