This chemokine is released from alpha-granules of activated platelets during platelet aggregation, and promotes blood coagulation by moderating the effects of heparin-like molecules. Due to these roles, it is predicted to play a role in wound repair and inflammation. It is usually found in a complex with proteoglycan.PF4 is chemotactic for neutrophils, fibroblasts and monocytes, and interacts with a splice variant of the chemokine receptor CXCR3, known as CXCR3B. PF4 is the antigen in heparin-induced thrombocyto.\u003c\/p\u003e\n\u003ch2\u003eAssay Principle\u003c\/h2\u003e\n\u003cp\u003eThis assay employs a two-site sandwich ELISA to quantitate PF-4 in samples. An antibody specific for PF-4 has been pre-coated onto a microplate. Standards and samples are pipetted into the wells and anyPF-4 present is bound by the immobilized antibody. After removing any unbound substances, a biotin-conjugated antibody specific for PF-4 is added to the wells. After washing, Streptavidin conjugated Horseradish Peroxidase (HRP) is added to the wells. Following a wash to remove any unbound avidin-enzyme reagent, a substrate solution is added to the wells and color develops in proportion to the amount of PF-4 bound in the initial step. The color development is stopped and the intensity of the color is measured.\u003c\/p\u003e\n\u003ch2\u003ePerformance Specifications\u003c\/h2\u003e\n\u003ctable class=\"bhp-spec-table\"\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003cth\u003eSensitivity\u003c\/th\u003e\n\u003ctd\u003e0.078 ng\/mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDetection Range\u003c\/th\u003e\n\u003ctd\u003e0.156-10 ng\/mL\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTotal Assay Time\u003c\/th\u003e\n\u003ctd\u003e3.5–5 hours\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCompatible Sample Types\u003c\/th\u003e\n\u003ctd\u003eserum, plasma, cell culture supernatant, tissue homogenate\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eSpecies Reactivity\u003c\/th\u003e\n\u003ctd\u003eHuman\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eDetection Method\u003c\/th\u003e\n\u003ctd\u003eColorimetric (TMB\/HRP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eStorage\u003c\/th\u003e\n\u003ctd\u003e4°C (short-term); -20°C (long-term)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\n\u003cp\u003e\u003cspan class=\"bhp-qc-badge\"\u003e✓ Research-Grade Validation\u003c\/span\u003e\u003c\/p\u003e\n\u003ch2\u003eSafety \u0026amp; Regulatory\u003c\/h2\u003e\n\u003cdiv class=\"bhp-warning-box\"\u003e\n\u003cstrong\u003eResearch Use Only (RUO).\u003c\/strong\u003e This product is intended for research purposes only and is not approved for diagnostic, therapeutic, or clinical use.\u003c\/div\u003e\n\u003cp\u003eHandle reagents in accordance with institutional biosafety guidelines.
