Used in biomedical research to measure levels of human plasminogen activator inhibitor-1 (PAI-1) in blood and tissue samples. It helps assess fibrinolysis regulation, which is critical in studying thrombosis, cardiovascular diseases, and metabolic disorders like obesity and type 2 diabetes. The kit is widely used in clinical labs and research settings to investigate the role of PAI-1 in inflammation, cancer progression, and fibrosis. Its high sensitivity allows detection of PAI-1 in serum, plasma, and cell culture supernatants, supporting both diagnostic and prognostic evaluations.
