Used in biomedical research to quantify levels of Plasminogen Activator Inhibitor-1 (PAI-1) in rat samples, this ELISA kit enables accurate measurement of PAI-1 concentration in plasma, serum, and cell culture supernatants. It is widely applied in studies related to fibrinolysis, thrombosis, and cardiovascular diseases. Researchers also use it in metabolic and inflammatory disease models, such as diabetes and obesity, where PAI-1 levels are elevated. The kit supports high-throughput screening and provides a reliable tool for assessing the role of PAI-1 in disease progression and therapeutic interventions.
