UR-11353

UR-11353 is a selective platelet activating factor (PAF) antagonist with long-lasting activity. UR-11353 inhibits PAF-induced platelet aggregation in rabbit platelet-rich plasma. UR-11353 inhibits PAF-induced hypotension in normotensive rats. UR-11353 protects against PAF-induced mortality in mice.

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.
