ELISA for Platelet Factor 4 (PF4) quantification in human platelet-depleted plasma. 96-test microplate kit. Research use only.

PF4 (CXCL4) is released from platelet α-granules upon platelet activation, making it a sensitive marker of platelet activation in research contexts. Elevated PF4 is observed in activated platelet states. PF4 also forms immunogenic complexes with heparin — the PF4/heparin complexes are the antigen in heparin-induced thrombocytopenia (HIT). This ELISA measures PF4 antigen independently of antibody status.
