Used in biomedical research to quantify thymine phosphorylase levels in human biological samples such as serum, plasma, and tissue lysates. This assay helps investigate the role of TP in angiogenesis, cancer progression, and inflammatory diseases. Commonly applied in oncology studies to assess tumor microenvironment activity and evaluate response to chemotherapy or anti-angiogenic treatments. Also used in drug development to monitor target expression and validate therapeutic efficacy in preclinical and clinical settings.
