Used in biomedical research to quantify platelet factor 4 (PF-4) levels in monkey plasma or serum samples. This ELISA kit supports studies on platelet activation, thrombosis, and immune responses in preclinical models. It is particularly valuable in vaccine and drug development research where platelet-related adverse events, such as vaccine-induced immune thrombotic thrombocytopenia (VITT), are assessed. The assay enables high-throughput, specific, and sensitive detection, facilitating research in infectious diseases, hematology, and immunology using non-human primate models.
