Product Information

Product Usage Information

This product is the carrier free version of product #59678. All data were generated using the same antibody clone in the standard formulation which contains BSA and glycerol.

This formulation is ideal for use with technologies requiring specialized or custom antibody labeling, including fluorophores, metals, lanthanides, and oligonucleotides. It is not recommended for ChIP, ChIP-seq, CUT&RUN or CUT&Tag assays. If you require a carrier free formulation for chromatin profiling, please contact us. Optimal dilutions/concentrations should be determined by the end user.

BSA and Azide Free antibodies are quality control tested by size exclusion chromatography (SEC) to determine antibody integrity.

Formulation

Supplied in 1X PBS (10 mM Na2HPO4, 3 mM KCl, 2 mM KH2PO4, and 140 mM NaCl (pH 7.8)). BSA and Azide Free.

For standard formulation of this product see product #59678

Storage

Store at -20°C. This product will freeze at -20°C so it is recommended to aliquot into single-use vials to avoid multiple freeze/thaw cycles. A slight precipitate may be present and can be dissolved by gently vortexing. This will not interfere with antibody performance.

Specificity / Sensitivity

AQP4 (D1F8E) XP® Rabbit mAb (BSA and Azide Free) recognizes endogenous levels of total AQP4.

Species Reactivity:

Human, Mouse, Rat

Source / Purification

Monoclonal antibody is produced by immunizing animals with 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 (8,9,10). 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).
