human ... AQP4(361)

General description

The water-specific channel Aquaporin 4 is located in various tissues including the gastro intestinal tract, kidney and brain. It is an osmoreceptor which regulates body water balance and mediates water flow within the central nervous system. The localization of AQ4 to astrocyte endfeet makes it an excellent marker for astrocyte distal processes.

Specificity

Recognizes Aquaporin 4.
The antibody has not yet been tested for cross-reactivity to other species. The immunogen shows 94% similarity to mouse, 88% to bovine, 86% to rabbit and 82% to human AQP4 (hAQP4).

Immunogen

Epitope: C-Terminus
Synthetic Linear Peptide

Application

Anti-Aquaporin 4 Antibody is an antibody against Aquaporin 4 for use in WB.

The homeostasis of the central nervous system is maintained by the blood-brain barrier (BBB). Angiopoietins (Ang-1/Ang-2) act as antagonizing molecules to regulate angiogenesis, vascular stability, vascular permeability and lymphatic integrity. However, the precise role of angiopoietin/Tie2 signaling at the BBB

Devic's neuromyelitis optica is an inflammatory demyelinating disorder normally restricted to the optic nerves and spinal cord. Since the identification of a specific autoantibody directed against aquaporin 4, neuromyelitis optica-immunoglobulin G/aquaporin 4 antibody, neuromyelitis optica has been considered an entity

Astrocyte communication is typically studied by two-dimensional calcium ion (Ca2+) imaging, but this method has not yielded conclusive data on the role of astrocytes in synaptic and vascular function. We developed a three-dimensional two-photon imaging approach and studied Ca2+ dynamics
