Used in biomedical research to quantify levels of urokinase-type plasminogen activator (u-PA) in mouse biological samples such as plasma, serum, urine, and tissue extracts. The kit supports studies related to fibrinolysis, extracellular matrix degradation, cell migration, and tissue remodeling. Commonly applied in cancer research to investigate tumor invasion and metastasis, as u-PA plays a key role in activating plasminogen to plasmin, which degrades extracellular matrix components. Also utilized in inflammation and autoimmune disease studies, where u-PA expression is linked to immune cell infiltration and tissue damage. The ELISA format allows for high sensitivity and specificity, enabling researchers to monitor u-PA concentration changes under experimental conditions or in response to therapeutic interventions.
