Used in biomedical research to quantify levels of puromycin-sensitive aminopeptidase (PSA) in human biological samples such as serum, plasma, and tissue lysates. This ELISA kit enables researchers to study PSA's role in protein metabolism, antigen processing, and its potential involvement in neurological disorders and cancer. It is suitable for monitoring disease progression and evaluating therapeutic responses in experimental settings. The assay provides a sensitive and specific means to measure PSA concentrations, supporting investigations into its physiological and pathological functions.
