This antibody is specific for Human Platelet Factor IV. AM31850PU-N (clone RTO) is seen to bind free PF4 in the absence of any bound Heparin. This is unlike AM31851PU-N (clone KKO), which binds PF4/heparin complexes to a similar degree as auto-antibodies found in individuals with Heparin-Induced Thrombocytopenia/Thrombosis (HIT/HITT).

Hintergrund
Platelet Factor IV (PF4) is a 70 aa protein released from the alpha granules of activated platelets. PF4 is synthesized by bone marrow megakaryocytes and stored in alpha granules as a non-covalent bound tetramer. Platelet factor IV binds with high affinity to heparin and plays a role in inflammation and wound repair. PF4 is a chemoattractant for neutrophils, monocytes and fibroblasts and has been reported to be an immunologic regulator that inhibits suppressor T-cell activity.Synonyms: C-X-C motif chemokine 4, CXCL4, Iroplact, Oncostatin-A, PF-4, SCYB4
