P-selectin (CD62P) is an adhesion molecule expressed on the activated endothelium and activated platelets that is involved in the initial
attachment of leukocytes to inflamed vascular endothelium.
P-selectin is constitutively present in alfa-granules of platelets and Weibel-Palade bodies of endothelial cells, and is mobilized to the cell surface after activation by thrombogenic and inflammatory mediators.

Immunoprecipitation of P-selectin from human platelets with P-sel.KO.2.2 and P-sel.KO.2.3 mAbs.
Human activated and surface biotinylated platelets were lysed and immunoprecipitated with P-sel.KO.2.2 and P-sel.KO.2.3 mAbs. A mAb against CD84 was used as positive control, and an irrelevant mAb as negative control. Samples were run on a SDS-PAGE gel under reducing conditions and blotted onto PVDF membrane.
Membrane was treated with HRP-avidin and the bands developed. Molecular weight markers (kDa) are indicated.
