| Overview |
| bs-70017r-100ul |
| Aquaporin 2 (Ser261) Antibody |
| WB, IP, IHC |
| Specific for endogenous levels of the ~29 kDa AQP2 protein phosphorylated at Ser261. Also recognizes the glycosylated form of AQP2 at ~37 kDa. Immunolabeling is blocked by preadsorption with the phosphopeptide used as antigen, but not by the corresponding non-phosphopeptide. |
| Human, Mouse, Rat |
| Dog, Bovine, Chicken, Non-Human Primate |
| Specifications |
| Unconjugated |
| Rabbit |
| Synthetic phospho-peptide corresponding to amino acid residues surrounding Ser261 of rat aquarporin 2, conjugated to keyhole limpet hemocyanin (KLH). |
| Ser261 |
| Polyclonal |
| IgG |
| Lot Dependent |
| Antigen Affinity purification from Pooled whole antiserum |
| 10 mM HEPES (pH 7.5), 150 mM NaCl, 100 µg per ml BSA and 50% glycerol. |
| Storage at -20°C is recommended, as aliquots may be taken without freeze/thawing due to presence of 50% glycerol. Stable for at least 1 year at -20°C. |

| Aquaporin 2 (AQP2) is a hormonally regulated water channel located in the renal collecting duct. Mutations in the AQP2 gene cause hereditary nephrogenic diabetes insipidus in humans (Iolascon et al.,2007). A vasopressin induced cAMP increase results in the phosphorylation of AQP2 at serine-256 and its translocation from the intracellular vesicles to the apical membrane of principal cells (van Balkom et al., 2002). Recently, serine-261 has been identified as a novel phosphorylation site on AQP2 and levels of phosphorylated S261 have been shown to decrease with vasopressin treatment suggesting its involvement in vasopressin-dependent AQP2 trafficking (Hoffert et al., 2007) |
