Used to measure the activity of Na/K-ATPase enzyme in biological samples such as cell lysates, tissue homogenates, and plasma. This ELISA kit is particularly useful in research related to ion transport, cellular metabolism, and membrane function. It enables detection of enzyme activity changes under pathological conditions like hypertension, heart failure, and kidney disease. Also applied in drug development to assess the impact of compounds on Na/K-ATPase function. Provides a reliable, sensitive, and high-throughput method for quantitative analysis in both basic research and clinical studies.
