Immunogen:
A 16 AA synthetic peptide within the C-terminal domain of rat Aquaporin-8 (Koyama et al. 1997; Ishibashi et al. 1997) was selected for antibody production. This domain is predicted to be cytoplasmic.

Background Information:
Water is a critical component of all living cells. Interestingly, tissue membranes show a great degree of water permeability. Mammalian red cells, renal proximal tubules, and descending thin limb of Henle are extraordinarily permeable to water. Water crosses hydrophobic plasma membranes either by simple diffusion or through a facilitative transport mechanism mediated by special protein "aquaporin". Over the last decade, genes for several members of aquaporin family have been cloned, expressed, and their distribution studied in many tissues. Aquaporin-0 or MIP26 (major intrinsic protein 26 kDa), and Aquaporin-1 (purified from red cells) also called CHIP-28 (channel forming integral protein, 28 kDa; 268 AA; gene locus 7p14) has been the foundation of the growing family of aquaporins. The lens specific Aquaporin-0 represents up to 80% of total lens membrane protein. Defects in MIP26 are a cause of autosomal dominant cataract. The cataract Fraser mutation (CAT-FR or Shriveled) is a transposon-induced splicing error that substitutes a long terminal repeat sequence for the c-terminus of MIP. The lens opacity mutation (LOP) is an AA substitution that inhibits targeting of MIP to the cell membrane. A new water channel, Aquaporin-8, has been identified in rat pancreas and testis by homology cloning (Koyama et al., 1997). Aquaporin-8 (263 aa; 28 kDa) is also found in liver, colon and salivary glands. Aquaporin-8 (APQ8) is expressed in all stages of spermatogenesis. Unlike other AQP, AQP8 has unusually long N-terminus and a short C-terminus. AQP families of proteins are predicted to contain six transmembrane domains. The N and C-terminus are predicted to be cytoplasmic. AQP8 has significant homology to various AQPs: g-TIP (plant water channel, 37%); AQP2 and MIP (37%), AQP1, AQP4, and AQP5 (30-34%); AQP3 (26%). AQP8 does not facilitate glycerol transport.

Application Notes:
Western blot: 1-10 μg/mL using ECL ELISA: 0.5-1.0 μg/mL Immunohistochemistry: We recommend using the affinity purified antibody at 2-10 μg/mL in paraformaldehyde fixed sections of tissues. *Note: It is recommended that 0.5-1% milk is used in all primary/secondary antibody-enzyme conjugate incubations in order to diminish non-specific binding. Optimal working dilutions must be determined by end user.

Entrez Gene Summary:
Aquaporin 8 (AQP8) is a water channel protein. Aquaporins are a family of small integral membrane proteins related to the major intrinsic protein (MIP or AQP0). Aquaporin 8 mRNA is found in pancreas and colon but not other tissues.
