AQP4 is an osmoreceptor that regulates water flow in the CNS. It is abundant in astrocytes, but is also weakly noticeable in pulmonary, intestinal, ocular and renal tissues. Rabbit Anti-Water Channel Aquaporin 4 antibody recognizes aquaporin 4 in human, mice and rats.
Immunogen
recombinant fusion protein corresponding to residues 249-323 of rat AQP4 fused to GST.
Application
Rabbit Anti-Water Channel Aquaporin 4 antibody can be used for immunohistochemical applications. The antibody can also be used for immunocytochemistry, western blot and flow cytometry applications.
Biochem/physiol Actions
Immunoprecipation and western blot analysis using HEK-293 cells that had been transfected with GFP-AQP4 was performed using rabbit anti-AQP4 as the primary antibody at 2μl/ml.
Physical form
Lyophilized from phosphate buffered saline, pH 7.4, containing 1% bovine serum albumin, and 0.05% sodium azide.

There is a constitutive production of water in brain. The efflux routes of this excess water remain to be identified. We used basal brain water content as a proxy for the capacity of water exit routes. Basal brain water content
Reports of neuromyelitis optica spectrum disorder (NMOSD) occurring in the setting of neoplasia suggest that aquaporin-4 autoimmunity may in some cases have a paraneoplastic basis. In this case report, we describe a patient with NMOSD whose test results were seropositive

The discovery of a highly specific antibody against the aquaporin-4 (AQP4) water channel (AQP4-IgG) unified the spectrum of neuromyelitis optica spectrum disorders (NMOSD), which are considered to be antibody-mediated autoimmune diseases. The AQP4 water channel is located on astrocytic end-feet

Ventriculomegaly (expansion of the brain's fluid-filled ventricles), a condition commonly found in the aging brain, results in areas of gliosis where the ependymal cells are replaced with dense astrocytic patches. Loss of ependymal cells would compromise trans-ependymal bulk flow mechanisms
