Used to measure the activity of H+-ATPase enzymes in plant cell membranes, this ELISA kit helps researchers study plant physiological processes such as nutrient uptake, stomatal regulation, and stress responses. It is widely applied in plant biology and agriculture research to evaluate how environmental factors like salinity, drought, or pH affect proton pump function. The kit enables quantitative analysis in root, leaf, or membrane extracts, supporting studies on plant growth mechanisms and crop resilience.
