General description
Aquaporin-5 (UniProt: P55064; also known as AQP-5) is encoded by the AQP5 gene (Gene ID: 362) in human. Aquaporins, a highly conserved group of membrane proteins that are involved in the bidirectional transfer of osmotically driven water and small solutes across cell membranes. They contain two tandem repeats each containing three membrane-spanning domains and a pore-forming loop with the signature motif Asn-Pro-Ala (NPA). Aquaporin-5 is a homotetrameric, multi-pass membrane glycoprotein that contains six cytoplasmic domains, six continuous transmembrane domains, two discontinuous transmembrane domains, and four extracellular domains. Its amino and carboxyl termini located in the cytoplasm. It is detected in skin eccrine sweat glands, digestive tract, renal cortex, and vaginal epithelial cells. In the respiratory system it is expressed in airways at the apical membrane of columnar epithelial cells and at the apical membrane of serous acinar cells of sub-mucosal glands. In lungs its expression at the apical membrane of type I pneumocytes. It plays an important role in fluid secretion in salivary glands and is shown to be essential for transient receptor potential cation channel subfamily V member 4) (TRPV4) activation by hypotonicity. Together with TRPV4 it controls regulatory volume decrease in salivary epithelial cells. Mutations in AQP5 gene have been linked to the development of palmoplantar keratoderma, a disease that is characterized by an abnormal thickening of the skin on the palms of the hands and soles of feet. Overexpression of Aquaporin-5 has also been observed in several human cancers and knockdown of AQP5 leads to partially reduced cell cycle progression from G1 to S phase and apoptosis. This ZooMAb® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.

Biochem/physiol Actions
Clone 3H17 is a Rabbit recombinant monoclonal antibody that specifically detects Aquaporin-5 in multiple species. It targets an epitope within 25 amino acids from the C-terminal, cytoplasmic domain.
Physical form
Purified recombinant rabbit monoclonal antibody IgG, lyophilized in PBS, 5% Trehalose, normal appearance a coarse or translucent resin. The PBS/trehalose components in the ZooMAb formulation can have the appearance of a semi-solid (bead like gel) after lyophilization. This is a normal phenomenon. Please follow the recommended reconstitution procedure in the data sheet to dissolve the semi-solid, bead-like, gel-appearing material. The resulting antibody solution is completely stable and functional as proven by full functional testing. Contains no biocide or preservatives, such as azide, or any animal by-products. Larger pack sizes provided as multiples of 25 μL.
Preparation Note
Recommend storage of lyophilized product at 2-8°C; Before reconstitution, micro-centrifuge vials briefly to spin down material to bottom of the vial; Reconstitute each vial by adding 25 μL of filtered lab grade water or PBS; Reconstituted antibodies can be stored at 2-8°C, or -20°C for long term storage. Avoid repeated freeze-thaws.
Reconstitute lyophilized antibody pellet with 25μL of ultrapure water or Phosphate Buffered Saline (PBS). Please refer to our reconstitution protocol and the specific application guidance on the suggested starting dilutions and sample type.
