    Product Information

    Product Description

    This Cell Signaling Technology® antibody retains the antigen-binding Fab regions of the original parent host sequence from which it is engineered. This antibody is expected to exhibit the same species cross-reactivity as AQP4 (D1F8E) Rabbit Monoclonal Antibody #59678.

    Product Usage Information

    Application Dilution
    Immunofluorescence (Frozen) 1:200 - 1:800

    Storage

    Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/mL BSA, 50% glycerol, and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

    Protocol

    Specificity / Sensitivity

    AQP4 (D1F8E) Mouse Chimeric Monoclonal Antibody recognizes endogenous levels of total AQP4.

    Species Reactivity:

    Human, Mouse, Rat

    Source / Purification

    This recombinant chimeric antibody is engineered from AQP4 (D1F8E) Rabbit Monoclonal Antibody #59678 according to animal-free protocols. The chimeric antibody retains its antigen-binding Fab regions from the original rabbit monoclonal antibody but contains a mouse-derived Fc domain. When multiplexing, Fc-directed rabbit secondaries are required to detect rabbit-host primary antibodies.

    The parent antibody, AQP4 (D1F8E) Rabbit Monoclonal Antibody #59678, is produced by immunizing animals with a recombinant protein specific to the carboxy terminus of human AQP4 protein.

    Background

    Aquaporins (AQPs) are integral membrane proteins that serve as channels to transfer water and small solutes across the membrane. There are 13 isoforms of AQP that are expressed in different types of cells and tissues (1,2). AQP1 is found in blood vessels, kidney, eye, and ear. AQP2 is found in the kidney, and it has been shown that the lack of AQP2 results in diabetes (1,3). AQP4 is present in the brain, where it is enriched in astrocytes (1,2,4). AQP5 is found in the salivary and lacrimal gland, AQP6 in intracellular vesicles in the kidney, AQP7 in adipocytes, AQP8 in kidney, testis, and liver, AQP9 is present in liver and leukocytes, and AQP10-11 in the intestine (1,3,4). AQPs are essential for the function of cells and organs. It has been shown that AQP1 and AQP4 regulate water homeostasis in astrocytes, preventing cerebral edema caused by solute imbalance (5). Several studies have shown the involvement of AQPs in the development of inflammatory processes, including innate and adaptive cell immunity (6,7).

    AQP4 is expressed in brain cells, including neurons, but enriched in astrocytes, as well as in the peripheral nervous system (4,7). AQP4 influences synaptic plasticity and the lack of this protein in the brain may cause memory and learning impairment via glutamate transporter 1 (GLT1) in Alzheimer's disease (8-10). It's suggested that AQP4 could play a role in the clearance of β-amyloid, and it may influence the transport of potassium and calcium in Alzheimer's disease (8,9). In Parkinson's disease, the lack of AQP4 results in an increased susceptibility of neurons from the substantia nigra and the ventral tegmental area for MPTP (11).
