Used for the detection and quantification of glutamate decarboxylase (GAD) enzyme activity in plant samples, this ELISA kit is essential in plant physiology and stress response studies. It enables researchers to monitor GAD levels under various environmental stresses such as drought, salinity, and pathogen attack, where GAD plays a key role in producing gamma-aminobutyric acid (GABA), a compound involved in plant defense and stress adaptation. The kit supports high-throughput analysis in agricultural research, helping in the development of stress-tolerant crop varieties. It is also used in post-harvest studies to assess plant metabolic changes during storage and ripening.
