Applications

Our Abpromise guarantee covers the use of ab81355 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
ICC/IF Use a concentration of 5 µg/ml.
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 35 kDa.

Target

  • 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%.

Images

  • ICC/IF image of ab81355 stained SKNSH cells. The cells were 4% formaldehyde fixed (10 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab81355, 5µg/ml) overnight at +4°C. The secondary antibody (green) was ab96899, DyLight® 488 goat anti-rabbit IgG (H+L) used at a 1/250 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.

  • All lanes : Anti-Aquaporin 4 antibody (ab81355) at 1 µg/ml

    Lane 1 : Tissue lysates prepared from Rat heart tissue.
    Lane 2 : Tissue lysates prepared from Rat kidney tissue.

Answer

Thank you for your enquiry.

I would like to reassure you that our antibodies have all been tested successfully and would be covered by our guarantee in the applications listed on the datasheets. Therefore, any Aquaporin 4 antibody tested in the species and application you are using should be suitable for your applications.

Also, although we produce many in-house antibodies, we obtain other antibodies from a wide range of sources. Therefore, comparison experiments will not often have been done. I would recommend that when a user is deciding upon a product that they look for those products which have Abreviews and have been used in publications, if possible. When choosing an antibody to be used in Western blot or Flow Cytometry I would also recommend choosing a product which has either a peptide available or the peptide sequence published as the peptide can be used for blocking if necessary.

Please let me know which product your customer would prefer. I look forward to hearing from you. Should you have any further questions please do not hesitate to ask.

Thank you for contacting us.






I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.
