PF4V1, also known as CXCL4L1, is a non-allelic variant of CXCL4. PF4V1 is a platelet-associated chemokine, and it binds to heparin is much weaker than in the close homolog PF4/CXCL4. PF4V1 is an inhibitor of angiogenesis and inhibitor of endothelial cell chemotaxis. PF4V1 is involved in inflammation, angiogenesis, and cancer[1][2]. PF4V1 Protein, Human (HEK293, Fc) is produced in HEK293 cells with a C-Terminal Fc-tag. It consists of 104 amino acids (M1-S104) .
