Used for the quantitative measurement of Glycine 1-Phosphotransferase (GPT) enzyme activity in plant tissue extracts. This ELISA kit enables researchers to assess plant stress responses, particularly in cases of abiotic stress such as drought, salinity, or heavy metal exposure, where GPT activity may change significantly. It is widely applied in agricultural research and plant physiology studies to evaluate plant health and metabolic changes under experimental conditions. The assay supports high-throughput analysis, making it suitable for screening plant varieties for stress tolerance in breeding programs.
