Platelet factor 4 (PF4) is released during platelet aggregation and neutralizes the anticoagulant effect of heparin with a higher binding affinity than chondroitin 4-sulfate chains. In addition to its anticoagulant effects, PF4 induces neutrophil and monocyte chemotaxis, thereby promoting immune responses. PF-4/CXCL4 Protein, Mouse is the recombinant mouse-derived Platelet factor 4 protein, expressed by E. coli , with tag free.
