Used in biomedical research to detect and quantify activated Factor II (FIIa), also known as thrombin, in rat plasma or serum samples. This ELISA kit is specifically designed for studying coagulation pathways and thrombotic disorders in rat models. It enables researchers to monitor thrombin generation, assess anticoagulant drug effects, and investigate mechanisms of hemostasis and thrombosis in preclinical studies. The assay is widely applied in pharmacology, cardiovascular research, and toxicology where accurate measurement of coagulation activity is essential. Due to its high sensitivity and specificity, it supports reliable data collection in experimental models of bleeding, clotting, and inflammatory diseases involving the coagulation cascade.
