This entire complex (capture antibody\/analyte\/detector antibody) is in turn immobilized via immunoaffinity of an anti-tag antibody coating the well. To perform the assay, samples or standards are added to the wells, followed by the antibody mix. After incubation, the wells are washed to remove unbound material. CatchPoint HRP Development Solution containing the Stoplight Red Substrate is added. During incubation, the substrate is catalyzed by HRP generating a fluorescent product. Signal is generated proportionally to the amount of bound analyte and the intensity is measured in a fluorescence plater reader at 530\/570\/590 nm Excitation\/Cutoff\/Emission.\u003cbr\u003e\nPlatelet factor-4 (PF4\/CXCL4) is a 70-amino acid protein that is released from the alpha-granules of activated platelets whose major physiologic role appears to be inhibiting local antithrombin III activity and promoting coagulation. PF4 has a role in inflammation and wound repair by acting as a strong chemoattractant for neutrophils, monocytes, and fibroblasts.\u003c\/p\u003e\n\n\u003cp\u003eProperties and Storage Information:\u003cbr\u003e\nShipped at conditions-Blue Ice, Appropriate short-term storage conditions-+4°C, Appropriate long-term storage conditions-+4°C, Storage information-+4°C\u003c\/p\u003e\n\n\u003cp\u003eSupplementary Information:\u003cbr\u003e\nThis supplementary information is collated from multiple sources and compiled automatically.\u003cbr\u003e\nThe 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.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPF4 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.\u003cbr\u003e\nPathways\u003cbr\u003e\nPF4 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.\u003cbr\u003e\nResearchers 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.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46843582021801,"sku":"ab278096","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/ar\/products\/abcam-ab278096","provider":"Iright","version":"1.0","type":"link"}
