General description

Platelet factor-4 (PF-4) or chemokine (C-X-C motif) ligand 4 is a CXC chemokine that is expressed in megakaryocytes and stored in the α-granules of platelets. Recombinant human CXCL4 protein, fused to His-tag at N-terminus, was expressed in E.coli and purified by using conventional chromatography techniques.

Biochem/physiol Actions

Platelet factor-4 (PF-4) or chemokine (C-X-C motif) ligand 4 is chemotactic towards neutrophils and monocytes and has been shown to inhibit angiogenesis. This protein associates with heparin and neutralizes it. It also neutralizes various negatively charged proteoglycans.

Physical form

0.25 mg/mL in 20 mM Tris-HCl buffer (pH 8.0) containing 0.2 M NaCl, 2 mM DTT and 50% glycerol.

Inhibitory receptors are crucial immune regulators and are essential to prevent exacerbated responses, thus contributing to immune homeostasis. Leukocyte associated immunoglobulin like receptor 1 (LAIR-1) is an immune inhibitory receptor which has collagen and collagen domain containing proteins as ligands....
