Used in biomedical research to quantify levels of Plasminogen Activator Inhibitor 1 (PAI-1) in biological samples such as plasma, serum, and cell culture supernatants. Enables researchers to study the role of PAI-1 in fibrinolysis, thrombosis, and cardiovascular diseases. Commonly applied in studies related to metabolic disorders, obesity, and type 2 diabetes due to elevated PAI-1 levels in these conditions. Also utilized in cancer research, as PAI-1 is involved in tissue remodeling and tumor progression. Supports investigation of inflammatory processes and fibrosis where SERPINE1 expression is upregulated. Provides a reliable, high-throughput method for monitoring therapeutic responses in experimental models targeting the plasminogen activation system.
