Used in biomedical research to measure levels of coagulation factor VIII in rat plasma or serum samples. This kit enables researchers to assess blood clotting function in experimental models, particularly in studies related to hemophilia A, thrombosis, and other coagulation disorders. It is commonly applied in preclinical studies evaluating the efficacy of new therapies, monitoring disease progression, or investigating the role of factor VIII in vascular biology. The ELISA format allows for sensitive and specific quantification, making it a valuable tool in pharmacological and physiological research involving hemostasis and coagulation pathways.
