Used in research settings to detect and quantify Aquaporin-0 (AQP-0) protein levels in human ocular tissue samples, particularly in studies related to lens physiology and cataract formation. The kit enables precise measurement of AQP-0 expression in aqueous humor or lens epithelial cells, supporting investigations into water homeostasis in the eye and the role of aquaporins in maintaining lens transparency. Commonly applied in ophthalmic research, developmental biology, and disease modeling where changes in AQP-0 levels may indicate early signs of lens degeneration or genetic disorders affecting the eye.
