Our Abpromise guarantee covers the use of ab110418 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

应用 Ab评论 说明
WB Use a concentration of 1 µg/ml. Detects a band of approximately 37 kDa (predicted molecular weight: 29 kDa).
ELISA Use at an assay dependent concentration.
IHC-P Use a concentration of 1 µg/ml. Perform heat mediated antigen retrieval with citrate buffer pH 6 before commencing with IHC staining protocol.


  • 功能Forms a water-specific channel that provides the plasma membranes of renal collecting duct with high permeability to water, thereby permitting water to move in the direction of an osmotic gradient.
  • 组织特异性Expressed in renal collecting tubules.
  • 疾病相关Diabetes insipidus, nephrogenic, autosomal
  • 序列相似性Belongs to the MIP/aquaporin (TC 1.A.8) family.
  • 结构域Aquaporins contain two tandem repeats each containing three membrane-spanning domains and a pore-forming loop with the signature motif Asn-Pro-Ala (NPA).
  • 翻译后修饰Ser-256 phosphorylation is necessary and sufficient for expression at the apical membrane. Endocytosis is not phosphorylation-dependent.
  • 细胞定位Apical cell membrane. Basolateral cell membrane. Cytoplasmic vesicle membrane. Golgi apparatus, trans-Golgi network membrane. Shuttles from vesicles to the apical membrane. Vasopressin-regulated phosphorylation is required for translocation to the apical cell membrane. PLEKHA8/FAPP2 is required to transport AQP2 from the TGN to sites where AQP2 is phosphorylated.

Anti-Aquaporin 2 (phospho S261) antibody 图像

  • IHC image of Aquaporin 2 (phospho S261) staining in Rat normal kidney formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab110418, 1µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

    Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution
    developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 29 kDa
    Observed band size : 37 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 23 kDa,57 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 16 minutes
    Aquaporin 2 contains a potential glycosylation site (SwissProt) which may explain its migration at a higher molecular weight than predicted. The predicted molecular weight of Aquaporin 2 is 29 kDa (SwissProt), however we expect to observe a banding pattern around 37 kDa. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
  • ab110418 was tested using an Indirect ELISA approach. The wells were coated with peptide (1µg/ml at 100µl/well) overnight at 4°C, followed by a 5% BSA blocking step for 1 hour at room temperature. The primary Ab was then added at a dilution range of 1- 0.00025µg/ml (100µl/well) for 1hr at room temperature. A HRP-conjugated anti-rabbit IgG (heavy and light chain) was used as a secondary antibody at 1:20,000 dilution for 1hr at room temperature.
