Used for the detection and quantification of Malic Dehydrogenase (MDH) enzyme activity in plant samples, this ELISA kit enables researchers to assess metabolic activity related to the tricarboxylic acid (TCA) cycle and malate metabolism. It is commonly applied in plant physiology studies to monitor stress responses, as MDH levels can change under abiotic stress conditions such as drought, salinity, or extreme temperatures. The kit supports high-throughput analysis in agricultural research and breeding programs aiming to develop stress-tolerant crop varieties. It is also useful in post-harvest studies, where changes in MDH activity correlate with fruit ripening and senescence processes.
