Used in biomedical research to detect and quantify Aquaporin-9 protein levels in rat tissue samples, particularly in studies related to liver function, brain physiology, and metabolic regulation. Helps researchers investigate the role of AQP-9 in water and solute transport, especially glycerol permeability, across cell membranes. Commonly applied in neuroscience and hepatology to explore disease mechanisms such as hepatic encephalopathy, fatty liver disease, and neuroinflammation. Provides a reliable, sensitive method for measuring AQP-9 expression changes in experimental models, supporting the development of targeted therapies.
