  • General notes





Our Abpromise guarantee covers the use of ab28668 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 0.125 µg/ml. Detects a band of approximately 70 kDa (predicted molecular weight: 70 kDa).Can be blocked with SCNN1B peptide (ab177197). Good results were obtained when blocked with 5% non-fat dry milk in 0.05% PBS-T.
ELISA 1/312500.
ICC/IF Use a concentration of 1 µg/ml.


  • Function
    Sodium permeable non-voltage-sensitive ion channel inhibited by the diuretic amiloride. Mediates the electrodiffusion of the luminal sodium (and water, which follows osmotically) through the apical membrane of epithelial cells. Controls the reabsorption of sodium in kidney, colon, lung and sweat glands. Also plays a role in taste perception.
  • Involvement in disease
    Pseudohypoaldosteronism 1, autosomal recessive
    Liddle syndrome
    Bronchiectasis with or without elevated sweat chloride 1
  • Sequence similarities
    Belongs to the amiloride-sensitive sodium channel (TC 1.A.6) family. SCNN1B subfamily.
  • Post-translational
    Phosphorylated on serine and threonine residues.
  • Cellular localization
    Apical cell membrane. Apical membrane of epithelial cells.

  • ab28668 stained HepG2 cells. The cells were 4% formaldehyde fixed for 10 minutes at room temperature and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1hour at room temperature to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab28668 at 1µg/ml) overnight at +4°C. The secondary antibody (pseudo-colored green) was Goat Anti-Rabbit IgG H&L (Alexa Fluor® 488) preadsorbed (ab150081) used at a 1/1000 dilution for 1hour at room temperature. Alexa Fluor® 594 WGA was used to label plasma membranes (pseudo-colored red) at a 1/200 dilution for 1hour at room temperature. DAPI was used to stain the cell nuclei (pseudo-colored blue) at a concentration of 1.43µM for 1hour at room temperature.

Customer reviews and Q&As


Thank you for completing the questionnaire and for including the western blotting image.
I am sorry this antibody is giving you trouble. It seems you should be able to detect SCNN1B from MCF7 cells. If you have purchased this antibody within the past 6 months or so I would be happy to offer a replacement, credit or refund.
Please let me know how you wish to proceed. In your reply, please include the PO number or Abcam order reference number so I can process your request.
