Specifications

Our Abpromise guarantee covers the use of ab46181 in the following tested applications.

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

  • Applications

    Blocking - Blocking peptide for Anti-Aquaporin 4 antibody (ab46182)

  • Form
    Liquid
  • Additional notes

    - First try to dissolve a small amount of peptide in either water or buffer. The more charged residues on a peptide, the more soluble it is in aqueous solutions.
    - If the peptide doesn’t dissolve try an organic solvent e.g. DMSO, then dilute using water or buffer.
    - Consider that any solvent used must be compatible with your assay. If a peptide does not dissolve and you need to recover it, lyophilise to remove the solvent.
    - Gentle warming and sonication can effectively aid peptide solubilisation. If the solution is cloudy or has gelled the peptide may be in suspension rather than solubilised.
    - Peptides containing cysteine are easily oxidised, so should be prepared in solution just prior to use.

  • Function
    Forms a water-specific channel. Osmoreceptor which regulates body water balance and mediates water flow within the central nervous system.
  • Tissue specificity
    Brain - muscle >> heart, kidney, lung, and trachea.
  • Sequence similarities
    Belongs to the MIP/aquaporin (TC 1.A.8) family.
  • Domain
    Aquaporins 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%.
  • Cellular localization
    Membrane.
  • Information by UniProt
