Application Abreviews Notes
WB Use at an assay dependent concentration. Predicted molecular weight: 11 kDa.
IP Use at an assay dependent concentration.


  • Function

    Released during platelet aggregation. Neutralizes the anticoagulant effect of heparin because it binds more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Chemotactic for neutrophils and monocytes. Inhibits endothelial cell proliferation, the short form is a more potent inhibitor than the longer form.
  • Sequence similarities

    Belongs to the intercrine alpha (chemokine CxC) family.
  • Post-translational

    Binds non-covalently to a proteoglycan molecule.
  • Cellular localization

  • PF4 was immunoprecipitated from 0.35 mg mouse serum lysate with ab182988 at 1/30 dilution. Western blot was performed from the immunoprecipitate using ab182988 at 1/1000 dilution. VeriBlot for IP Detection Reagent (HRP) (ab131366) was used for detection at 1/10,000 dilution.
    Lane 1: Mouse serum lysate 10 µg (Input).
    Lane 2: ab182988 IP in mouse serum lysate (+).
    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab182988 in mouse serum (-).
    Blocking and dilution buffer and concentration: 5% NFDM/TBST.
    Exposure time: 1 second.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab182988).
