Used in biomedical research to detect and quantify platelet factor 4 (PF4) levels in rat samples, this ELISA kit supports studies on thrombosis, inflammation, and immune responses involving platelets. It is particularly valuable in preclinical research assessing drug-induced platelet activation or evaluating the mechanisms of heparin-induced thrombocytopenia (HIT) in rodent models. The kit enables high-throughput, sensitive measurement of PF4, facilitating investigation into platelet release reactions and vascular biology in experimental settings.
