products description :
Platelet factor IV 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. (clone RTO) is seen to bind free PF4 in the absence of any bound heparin. This is unlike (clone KKO), which binds PF4/heparin complexes to a similar degree as auto-antibodies found in individuals with Heparin-Induced Thrombocytopenia/Thrombosis (HIT/HITT).

uniprot summary :
Function: Inhibitor of angiogenesis. Inhibitor of endothelial cell chemotaxis (in vitro). Ref.5. Subunit structure: Homotetramer. Ref.6. Subcellular location: Secreted. Post-translational modification: The N-terminal processed forms of platelet factor 4 variant seems to be produced by proteolytic cleavage. The most abundant form is Platelet factor 4 variant(5-74). Miscellaneous: Binding to heparin is much weaker than in the close homolog PF4/CXCL4. Sequence similarities: Belongs to the intercrine alpha (chemokine CxC) family. Mass spectrometry: Molecular mass is 8250.9 Da from positions 31 - 104. Determined by ESI. Platelet factor 4 variant. Ref.5Molecular mass is 7877.7 Da from positions 34 - 104. Determined by ESI. Platelet factor 4 variant(4-74). Ref.5Molecular mass is 7805.8 Da from positions 35 - 104. Determined by ESI. Platelet factor 4 variant(5-74). Ref.5Molecular mass is 7678.6 Da from positions 36 - 104. Determined by ESI. Platelet factor 4 variant(6-74). Ref.5
