产品详情

Abcam's PF4 (CXCL4) Human ELISA (Enzyme-Linked Immunosorbent Assay) kit is an in vitro enzyme-linked immunosorbent assay for the quantitative measurement of Human PF4 in serum, plasma, and cell culture supernatants.

This assay employs an antibody specific for Human PF4 coated on a 96-well plate. Standards and samples are pipetted into the wells and PF4 present in a sample is bound to the wells by the immobilized antibody. The wells are washed and biotinylated anti-Human PF4 antibody is added. After washing away unbound biotinylated antibody, HRP-conjugated streptavidin is pipetted to the wells. The wells are again washed, a TMB substrate solution is added to the wells and color develops in proportion to the amount of PF4 bound. The Stop Solution changes the color from blue to yellow, and the intensity of the color is measured at 450 nm.

Get results in 90 minutes with Human PF4 ELISA Kit (CXCL4) (ab189573) from our SimpleStep ELISA^® range.

Optimization may be required with urine samples.

补充信息

This supplementary information is collated from multiple sources and compiled automatically.

The protein Platelet Factor 4 (PF4) also known as CXCL4 is a member of the chemokine (C-X-C motif) ligand family. This small protein has a molecular weight of approximately 7.8 kDa. PF4 is mainly expressed in megakaryocytes and stored in the alpha granules of platelets. During platelet activation PF4 releases into the bloodstream where it interacts with other proteins and cell types. Researchers measure PF4 levels with methods such as PF4 ELISA to study its expression and functions under various physiological and pathological conditions.

Biological function summary

PF4 plays an important role in modulating the immune response and coagulation processes. PF4 is not part of a stable protein complex but can interact dynamically with heparin on the surface of endothelial cells and glycosaminoglycans. It inhibits the action of heparin promoting clot formation and angiogenesis. PF4 also attracts and activates different types of leukocytes and can regulate inflammatory processes influencing how the immune system responds to injury.

Pathways

PF4 significantly interacts with both the coagulation and inflammation pathways. In the coagulation pathway PF4 acts to neutralize heparin-like molecules thereby enhancing thrombosis. It works closely with proteins such as thrombin and fibrinogen contributing to the blood clot cascade. Within the inflammatory pathway PF4's chemokine activity helps direct leukocytes to sites of tissue damage or infection linking it to cytokines and other chemokines that mediate immune responses.

Researchers associate PF4 with conditions such as thrombosis and autoimmune pathologies. In thrombosis the overexpression of PF4 can lead to excessive clot formation pointing to its interaction with proteins like thrombin. PF4 also plays a role in heparin-induced thrombocytopenia (HIT) a disorder where the immune system mistakenly produces antibodies against heparin-PF4 complexes further indicating its direct involvement with immune and coagulation pathways.

靶点信息

Chemokine released during platelet aggregation that plays a role in different biological processes including hematopoiesis, cell proliferation, differentiation, and activation (PubMed : 29930254, PubMed : 9531587). Acts via different functional receptors including CCR1, CXCR3A or CXCR3B (PubMed : 18174362, PubMed : 29930254). Upon interaction with CXCR3A receptor, induces activated T-lymphocytes migration mediated via downstream Ras/extracellular signal-regulated kinase (ERK) signaling (PubMed : 18174362, PubMed : 24469069). Neutralizes the anticoagulant effect of heparin by binding more strongly to heparin than to the chondroitin-4-sulfate chains of the carrier molecule. Plays a role in the inhibition of hematopoiesis and in the maintenance of hematopoietic stem cell (HSC) quiescence (PubMed : 9531587). Chemotactic for neutrophils and monocytes via CCR1 (PubMed : 29930254). Inhibits endothelial cell proliferation. In cooperation with toll-like receptor 8/TLR8, induces chromatin remodeling and activates inflammatory gene expression via the TBK1-IRF5 axis (PubMed : 35701499). In addition, induces myofibroblast differentiation and collagen synthesis in different precursor cells, including endothelial cells, by stimulating endothelial-to-mesenchymal transition (PubMed : 34986347). Interacts with thrombomodulin/THBD to enhance the activation of protein C and thus potentiates its anticoagulant activity (PubMed : 9395524).
