Human Aquaporin 2, Collecting Duct (AQP2) ELISA Kit

AQP2 is a vasopressin-regulated water channel localized to the apical membrane of renal collecting duct principal cells, where it governs final urine concentration. Measuring AQP2 in human samples provides insight into mechanisms of water balance disorders, including nephrogenic diabetes insipidus and syndrome of inappropriate antidiuretic hormone secretion. This Assay Genie ELISA kit is formatted for 96 assays and quantifies human Aquaporin 2 in tissue homogenates and urine using a colorimetric readout. The kit supports renal physiology research, biomarker discovery, and investigations of aquaretic drug pharmacology in laboratory settings. Researchers studying collecting duct function, vasopressin signaling, or polyuria and polydipsia can incorporate this product into standard plate-based immunoassay workflows as a research-use-only tool for in vitro studies.
