Used in biomedical research to measure levels of Protein Tyrosine Phosphatase 1B (PTP-1B) in cell lysates, tissue extracts, and biological fluids. This kit enables researchers to study the role of PTP-1B in insulin signaling, obesity, type 2 diabetes, and cancer. It is commonly applied in drug development to evaluate the effectiveness of PTP-1B inhibitors. The assay provides a quantitative method to monitor changes in PTP-1B expression under different experimental conditions, supporting studies in metabolic disorders and cellular regulation pathways.
