Applications

Our Abpromise guarantee covers the use of ab46182 in the following tested applications.

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

Application Abreviews Notes
WB Use a concentration of 1 µg/ml. Detects a band of approximately 48 kDa (predicted molecular weight: 35 kDa).Can be blocked with Human Aquaporin 4 peptide (ab46181). Abcam recommends using milk as the blocking agent.
ICC/IF Use at an assay dependent concentration.
IHC-FrFl Use at an assay dependent concentration.
ICC Use at an assay dependent concentration.

Target

  • FunctionForms a water-specific channel. Osmoreceptor which regulates body water balance and mediates water flow within the central nervous system.
  • Tissue specificityBrain - muscle >> heart, kidney, lung, and trachea.
  • Sequence similaritiesBelongs to the MIP/aquaporin (TC 1.A.8) family.
  • DomainAquaporins contain two tandem repeats each containing three membrane-spanning domains and a pore-forming loop with the signature motif Asn-Pro-Ala (NPA).
  • Post-translational
    modifications
    Phosphorylation by PKC at Ser-180 reduces conductance by 50%. Phosphorylation by PKG at Ser-111 in response to glutamats increases conductance by 40%.

  • ab46182 staining Aquaporin 4 in mouse RAW 264.7 cells by Immunocytochemistry/ Immunofluorescence.
    Cells were fixed with paraformaldehyde and blocked with 10% serum for 20 minutes at 24°C. Samples were incubated with primary antibody (1/100 in PBS) for 16 hours at 4°C. An Alexa Fluor® 488-conjugated goat anti-rabbit polyclonal (1/1000) was used as the secondary antibody.

We recently compared this antibody against two other antibodies to Aquaporin 4 and they all gave a single band at about 46kDa. However a doublet at 46/48kDa is commonly seen when blotting for this target so if this is what you are seeing then I feel th...
