General description

The Human PF-4 (Platelet Factor-4) ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of human PF-4 in serum, plasma, cell culture supernatants and urine.

Immunogen

Recombinant Human PF4

Application

For research use only. Not for use in diagnostic procedures.
Human Platelet Factor-4 (PF4)/ CXCL4 (chemokine (C-X-C motif) ligand 4) ELISA Kit has been used to measure PF-4 / CXCL4 serum level in chronic myelomonocytic leukemia (CMML) patients.
Human Platelet Factor-4 / CXCL4 ELISA Kit has also been used in the measurement of platelet factor-4 in serum samples of prostate cancer and pseudoxanthoma elasticum patients.

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 other negatively charged proteoglycans. PF-4 / CXCL4 is implicated in cancer development. PF-4 regulates the activity of proangiogenic growth factors. PF-4 / CXCL4 function as a biomarker for systemic sclerosis and early tumor growth. PF-4 / CXCL4 is associated with various pathological conditions such as atherosclerosis, liver fibrosis and inflammation.

Heparin-induced thrombocytopenia (HIT) is an adverse immune-mediated response to unfractionated heparin and, less commonly, low molecular weight heparin. It is associated with a high thrombotic risk and the potential for limb and life-threatening complications. Argatroban is the only approved and

Heparin induced-thrombocytopenia (HIT) has been well recognized in Western countries. However, there are no data in the Thai population. We therefore investigated the prevalence of anti-platelet factor 4 (PF4)/heparin antibodies, HIT, and its thrombotic complications in Thai patients undergoing cardiac
