Used in research settings to quantify mouse platelet factor 4 (PF-4) levels in biological samples such as plasma, serum, or cell culture supernatants. This ELISA kit enables scientists to study platelet activation and immune responses in mouse models, particularly in thrombosis, inflammation, and autoimmune disease research. It is also valuable in studies related to heparin-induced thrombocytopenia (HIT) and other coagulation disorders. The assay provides a sensitive and specific means to monitor PF-4 release during experimental treatments, helping assess the role of platelets in disease mechanisms and therapeutic interventions.
