More Info

  • Introduction

    Platelet factor-4 is a 70-amino acid protein that is released from the alpha-granules of activated platelets and binds with high affinity to heparin. Its major physiologic role appears to be neutralization of heparin-like molecules on the endothelial surface of blood vessels, thereby inhibiting local antithrombin III activity and promoting coagulation. As a strong chemoattractant for neutrophils and fibroblasts, PF4 probably has a role in inflammation and wound repair. Oncostatin-A is a member of the CXC chemokine family. Human PF4 is used for the proof of heparin-induced thrombocytopenia. Furthermore it is used as an inhibitor in the angiogenesis during tumor therapy.

  • Synonyms

    CXCL4, PF-4, PF4, Iroplact, Oncostatin-A, SCYB4, MGC138298.

  • Physical Appearance

    Sterile Filtered white lyophilized powder.

  • Stability

    Human CXCL4 although stable at 25°C 1 week, should be stored desiccated below -18°C. Please prevent freeze-thaw cycles.

  • Solubility

    It is recommended to reconstitute the lyophilized CXCL4 in sterile 18MΩ-cm H2O not less than 100µg/ml, which can then be further diluted to other aqueous solutions.

  • Amino Acid Sequence

    The sequence of the first four N-terminal amino acids was determined and was found to be Glu-Ala-Glu-Glu.
