Used to measure the enzymatic activity of O-GlcNAc transferase (OGT) in human cell or tissue samples. This kit enables researchers to quantify changes in OGT activity in various biological conditions such as diabetes, cancer, and neurodegenerative diseases. It is commonly applied in studies related to post-translational modifications, cellular signaling, and metabolic regulation. The assay supports high-throughput screening and drug development by assessing how potential therapeutics affect OGT function. Results are useful in both basic research and clinical biomarker discovery.
