Used for the quantitative measurement of protein phosphatase (PP) activity in mouse biological samples such as tissue lysates, cell extracts, and serum. This ELISA kit enables researchers to assess PP enzyme function in signaling pathways related to cell growth, apoptosis, and metabolism. It is commonly applied in studies of diseases like diabetes, neurodegenerative disorders, and cancer where PP activity is dysregulated. The assay provides a sensitive and specific colorimetric readout, allowing high-throughput analysis in experimental and preclinical research settings.
