Used in plant biology research to measure the activity and expression levels of H+-ATPase enzymes in plant cells. These enzymes play a key role in maintaining cellular pH, nutrient uptake, and membrane potential. The kit enables researchers to quantify H+-ATPase in root tissues, leaves, and other plant parts under various environmental conditions such as salinity, drought, or nutrient stress. It supports studies on plant growth mechanisms, stress responses, and rhizosphere interactions by providing a reliable method to assess proton pump activity. Commonly used in agricultural research and plant physiology labs to evaluate plant health and adaptation strategies.
