  • Function

    Membrane-cytoskeleton-associated protein that promotes the assembly of the spectrin-actin network. Binds to calmodulin.
  • Tissue specificity

    Expressed in all tissues. Found in much higher levels in reticulocytes than the beta subunit.
  • Sequence similarities

    Belongs to the aldolase class II family. Adducin subfamily.
  • Domain

    Each subunit is comprised of three regions: a NH2-terminal protease-resistant globular head region, a short connecting subdomain, and a protease-sensitive tail region.
  • Cellular localization

    Cytoplasm > cytoskeleton. Cell membrane.

  • labelled with ab53093, at 1/50 dilution, staining alpha Adducin in paraffin embedded human brain tissue sections by Immunohistochemistry. Tissues had either been treated with (right image) or without (left image) the phosphopeptide.
  • ab53093 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 ab53093 at 5µg/ml overnight at +4°C. The secondary antibody (green) was DyLight® 488 goat anti- rabbit (ab96899) IgG (H+L) used at a 1/1000 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.

I can send you a replacement vial of an anti-adducin antibody of your choice as we do not stock small sample sizes. So I can process your request, please include your PO number or Abcam order reference number associated with the purchase of ab51130, along with your choice of antibody, in your reply.

Thank you for your enquiry and for providing the attached western blot data.

Here are a few points to consider:

1. Since a small, non-phosphorylated peptide was used as the immunogen for ab51130, itwill not be reactive with total adducin, only adducin which is not phosphorylated around S726. Phosphorylation at S726 will block biniding of ab51130. So in general this antibody is not a good choice for detecting "total" adducin.

I am currently checking our anti-adducin products to determine if we have an antibody that could be used as a 'total adducin antibody". I will reply as soon as I hear back from the lab.

2. As acontrol, consider treating membrane with phosphatase. This would remove any phosphorylation events and ensure the phosphorylation status is known prior to blotting.

Please see the attached phosphatase treatment protocol as an example.

3. Sodium pervanadate is a tyrosine phosphatase inhibitor. it should not have any effect on phosphorylation status of Ser726. Perhaps something unexpected is occuring due to addition of inhibitors.

I hope this is helpful. Please contact me if you have further questions.
