Used in plant physiology research to quantify NADP-malate dehydrogenase enzyme levels in plant tissues. This kit enables researchers to study the regulation of the photosynthetic process, particularly in C4 and CAM plants where NADP-MDH plays a key role in carbon fixation and malate metabolism. It is widely applied in studies related to plant stress responses, stomatal movement, and light-dependent enzyme activation. The assay helps in understanding how environmental factors like drought, salinity, and temperature affect photosynthetic efficiency by measuring changes in NADP-MDH concentration. Suitable for use with leaf extracts and other plant samples in agricultural and biochemical research.
