Used in biomedical research to quantify rat plasminogen levels in biological samples such as plasma, serum, or tissue homogenates. This kit enables researchers to study the role of plasminogen in fibrinolysis, inflammation, wound healing, and tumor progression in rat models. It is particularly valuable in preclinical studies assessing the impact of drugs or disease states on the plasminogen-plasmin system. The assay provides a reliable and sensitive method for measuring plasminogen concentration, supporting research in cardiovascular diseases, cancer, and immune responses.
