Used to measure the activity of calcium-magnesium-dependent ATPase (Ca-Mg-ATPase) enzymes in plant samples. This kit helps researchers assess membrane integrity and ion transport efficiency, which are critical in studying plant responses to environmental stresses such as salinity, drought, and heavy metal toxicity. It is widely applied in plant physiology and biochemistry research to evaluate cellular energy metabolism and enzyme function under various experimental conditions. The assay enables high-throughput analysis, making it suitable for screening plant varieties for stress tolerance or studying the effects of nutrients and inhibitors on ATPase activity.
