Used in biomedical research to detect and quantify Aquaporin-5 protein levels in rat tissue samples, particularly in studies related to fluid transport across membranes. Commonly applied in respiratory, salivary gland, and ocular research to investigate diseases involving abnormal water channel activity. Enables researchers to assess AQP-5 expression changes in response to inflammation, infection, or therapeutic interventions. Provides a reliable, sensitive method for measuring protein concentration in biological fluids or cell lysates, supporting mechanistic studies and biomarker development.
