Used in biomedical research to quantitatively measure levels of Human Coagulation Factor II (prothrombin) in plasma, serum, or other biological samples. This ELISA kit is essential for studying blood coagulation pathways, diagnosing coagulation disorders, and evaluating the effectiveness of anticoagulant therapies. It supports research in hematology, cardiovascular diseases, and thrombosis by providing a sensitive and specific method to monitor prothrombin concentration, which is critical for accurate assessment of liver function and vitamin K status. Widely used in laboratory settings for clinical diagnostics and pharmaceutical development.
