Used in biomedical research to quantify levels of plasminogen activator inhibitor-1 (PAI-1) in mouse samples such as plasma, serum, or cell culture supernatants. This assay helps study fibrinolysis, thrombosis, and cardiovascular diseases. It is also applied in research on metabolic disorders, inflammation, and cancer progression, where PAI-1 plays a role in tissue remodeling and cell migration. The kit enables high-throughput, accurate measurement, supporting both basic science and preclinical studies.
