Used for the quantitative measurement of malate dehydrogenase (MDH) enzyme activity in plant tissue extracts. This ELISA kit enables researchers to assess mitochondrial and chloroplastic MDH function, which plays a key role in the tricarboxylic acid (TCA) cycle and photosynthetic metabolism. It is commonly applied in plant physiology studies, stress response research, and metabolic engineering to evaluate plant health, energy metabolism, and adaptation to environmental stresses such as drought, salinity, or extreme temperatures. The assay is suitable for high-throughput analysis and provides a sensitive and specific method to monitor changes in MDH levels across different plant species and experimental conditions.
