Used to measure the activity of plant H-ATPase enzymes in research settings, particularly in plant physiology and molecular biology. Helps scientists study ion transport, nutrient uptake, and cellular pH regulation in plant cells. Widely applied in studies of plant stress responses, such as salinity, drought, and heavy metal exposure, where H-ATPase activity plays a key role in maintaining cellular homeostasis. Enables quantitative analysis of enzyme activity changes under different experimental conditions, supporting advancements in crop improvement and sustainable agriculture.
