Used for the quantitative measurement of acylamino acid hydrolase (AAT) enzyme activity in plant tissue extracts. This ELISA kit enables researchers to assess plant stress responses, as AAT activity is linked to metabolic changes during environmental stress such as drought, pathogen attack, or nutrient deficiency. It is commonly applied in agricultural research and plant physiology studies to evaluate plant health and defense mechanisms. The assay is suitable for high-throughput screening of plant samples, supporting breeding programs and functional genomics work aimed at improving stress tolerance in crops.
