Used in plant physiology research to quantify γ-aminobutyrate aminotransferase (GABAT) enzyme levels, this ELISA kit enables scientists to study the GABA shunt pathway, which plays a critical role in plant stress responses, nitrogen metabolism, and energy production. It is particularly valuable in experiments assessing how plants respond to abiotic stresses such as drought, salinity, and hypoxia. Researchers use the kit to measure changes in GABAT activity during different developmental stages or under various environmental conditions, helping to understand metabolic regulation in crops and model plants. The assay supports high-throughput analysis, making it suitable for screening plant varieties with enhanced stress tolerance or improved metabolic efficiency.
