Used in research settings to quantify levels of thrombotic precursor protein (TpP) in rat plasma or serum samples. This ELISA kit enables detection of early coagulation activity, making it valuable for studies related to thrombosis, cardiovascular diseases, and hemostasis in preclinical animal models. It supports evaluation of drug effects on platelet activation and clot formation, particularly in anti-thrombotic therapy development. The assay is also applied in toxicology and pharmacokinetic studies where blood coagulation changes may indicate compound-induced vascular injury.
