Used in biomedical research to quantify tripeptidyl peptidase 2 (TPP2) enzyme levels in human biological samples such as serum, plasma, and cell lysates. The kit enables researchers to study TPP2's role in intracellular protein degradation, immune response regulation, and its involvement in neurodegenerative diseases and cancer. It is also applied in clinical studies investigating autoimmune disorders and lysosomal storage diseases where TPP2 activity may be altered. The assay supports high-throughput analysis with high sensitivity and specificity, making it suitable for both basic research and diagnostic development.
