Used in biomedical research to quantify rat urokinase (UK) levels in biological samples such as plasma, serum, or tissue homogenates. This ELISA kit is particularly valuable in studies related to fibrinolysis, thrombosis, and cell migration, where urokinase plays a key role in plasminogen activation. It enables researchers to assess changes in urokinase concentration under experimental conditions, supporting investigations in inflammation, cancer metastasis, and cardiovascular diseases. The assay provides high specificity and sensitivity, making it suitable for monitoring urokinase expression in rodent models.
