CXCL4, Human

Sequence: EAEEDGDLQC LCVKTTSQVR PRHITSLEVI KAGPHCPTAQ LIATLKNGRK ICLDLQAPLY with polyhistidine tag at the N-terminus Endotoxin level: <0.1 EU per 1 µg of the protein by the LAL method. Protein function: Released during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation, the short form is a more potent inhibitor than the longer form. [The UniProt Consortium]
