Anti-AQP4 Antibody

Aquaporin-4 (AQP4) is the predominant water channel in the central nervous system, concentrated at astrocyte foot processes where it regulates water homeostasis across the blood-brain barrier. This unconjugated Rabbit Polyclonal antibody from Antibodies.com targets AQP4 and is validated for Western blot (WB), immunohistochemistry (IHC), and ELISA workflows across Human, Mouse, and Rat samples. Supplied as a 100 µl vial of polyclonal sera, the reagent supports frozen tissue section staining and standard lysate preparation. Its broad species reactivity makes it useful for cross-species comparative studies of AQP4 distribution in glial cells, kidney collecting ducts, and skeletal muscle, as well as for translational research into neuromyelitis optica and related astrocytopathies. Produced in a Rabbit host, the antibody enables flexible secondary antibody selection in multiplex labelling protocols.
