Used in biomedical research to quantify human plasminogen levels in biological samples such as plasma, serum, and cell culture supernatants. This ELISA kit enables researchers to study plasminogen's role in fibrinolysis, tissue remodeling, inflammation, and cancer progression. It is particularly valuable in studies related to thrombolytic disorders, wound healing, and angiogenesis. The assay provides a sensitive and specific means to monitor changes in plasminogen concentration under experimental conditions, supporting both clinical research and drug development.
