PF4V1 Recombinant Protein

Source : Escherichia Coli. PF4V1 Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 97 amino acids (31-104 a.a.) and having a molecular mass of 10.6kDa.PF4V1 is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Platelet Factor 4 Variant 1 (PF4V1) is a member of the intercrine alpha (chemokine CxC) family. PF4V1 is an inhibitor of angiogenesis and inhibitor of endothelial cell chemotaxis (in vitro) . PF4V1 binding to heparin is much weaker than in the close homolog PF4/CXCL4.
