Background: P2RY12 or P2Y12 is a G-protein coupled receptor for ADP and ATP. ADT released from platelets acts in a positive feedback mechanism on P2Y12 and P2Y1 on platelets and is critical for sustained aggregation and stabilization of thrombin. P2Y12 receptor plays a central role in platelet activation and is the target of of antithrombotic drugs such as ticlopidine and clopidogrel.
Application: Functional assays
