Change of P-selection expression(platelet activation-dependent granule membrane) at different time points.

Change of PAC-1 expression (platelet-associated complement) on the activated platelets at different time points.

Change of P2Y12 acceptor expression on platelets at different time points. (P2Y12 acceptor is a receptor for ADP(adenosine diphosphate) and ATP (adenosine triphosphate )coupled to G-proteins that inhibit the adenylyl cyclase second messenger system)
