Used in plant physiology research to quantify the expression and activity levels of plasma membrane H+-ATPase, a key enzyme involved in nutrient uptake, stomatal regulation, and plant stress responses. The ELISA kit enables precise measurement of protein concentration in plant tissue extracts, supporting studies on plant growth mechanisms, abiotic stress tolerance (such as salinity and drought), and hormone signaling. It is widely applied in agricultural research and crop improvement programs to evaluate how environmental and genetic factors influence membrane transport processes.
