Anti-AQP4 Antibody

A reliable rabbit polyclonal reagent from Antibodies.com targets aquaporin-4 (AQP4), the predominant water-selective channel protein expressed on astrocytic endfeet in the central nervous system. Supplied as 50 µl of liquid at 1.0 mg/mL concentration, this unconjugated antibody was raised against recombinant human AQP4 protein and affinity-purified using the immunogen. It is validated for Western blot (WB) and immunohistochemistry (IHC) and shows reactivity with human, mouse, and rat samples, making it useful for studies of brain water homeostasis, astrocyte biology, and blood–brain barrier function. The product is formulated in phosphate-buffered saline (without Mg²⁺ and Ca²⁺) at pH 7.4, containing 150 mM NaCl, 0.02% sodium azide as preservative, and 50% glycerol for added stability. Upon delivery the vial should be stored refrigerated, and for long-term storage it should be kept at -20 °C with care to avoid repeated freeze/thaw cycles. Intended for research use only, this AQP4 reagent is part of the Antibodies.com primary antibody portfolio and is dispatched from St. Louis, MO, allowing laboratories to consistently detect endogenous levels of total AQP4 protein across the listed species in WB and IHC workflows.
