Used to measure the activity of Tyrosine Aminotransferase (TAT) in plant samples, this ELISA kit is essential for researchers studying plant metabolism, stress responses, and hormone regulation. It enables accurate quantification of TAT levels in leaf extracts, seedlings, or other plant tissues, supporting work in plant physiology and genetic engineering. The assay is commonly applied in experiments involving abiotic stress such as drought, salinity, or temperature extremes, where changes in TAT activity can indicate shifts in amino acid metabolism and photorespiration. It is also useful in studies of circadian rhythms and light-regulated gene expression in plants. The kit provides a reliable, high-throughput method for monitoring enzyme activity in agricultural research and plant biotechnology.
