Used for the quantitative determination of thymidine phosphorylase (TPS) activity in mouse biological samples such as serum, plasma, or tissue homogenates. This ELISA kit enables researchers to measure TPS levels in studies related to tumor metabolism, angiogenesis, and cancer progression, particularly in mouse models of human diseases. It is a valuable tool in oncology and immunology research where TPS expression correlates with tumor burden and response to therapy. The assay provides high sensitivity and specificity, allowing accurate detection of TPS activity changes in experimental conditions.
