  • Function
    Receptor for globular and full-length adiponectin (APM1), an essential hormone secreted by adipocytes that acts as an antidiabetic. Probably involved in metabolic pathways that regulate lipid metabolism such as fatty acid oxidation. Mediates increased AMPK, PPARA ligand activity, fatty acid oxidation and glucose uptake by adiponectin. Has some intermediate-affinity receptor activity for both globular and full-length adiponectin.
  • Tissue specificity
    Highly expressed in skeletal muscle, liver and placenta. Weakly expressed in brain, heart, colon, spleen, kidney, thymus, small intestine, peripheral blood leukocytes and lung.
  • Sequence similarities
    Belongs to the ADIPOR family.
  • Domain
    The N-terminus is known to be cytoplasmic while the C-terminus is known to be extracellular.
  • Cellular localization
    Membrane. Localized to the cell membrane and intracellular organelles.

Thank you for contacting us and your interest in our products.

As you have seen on the datasheets for the anti-Adiponectin Receptor 2 antibody (ab77612) and anti-Adiponectin Receptor 1 antibody [EPR6626] (ab126611) have both been used in flow cytomertry. The data observed with the antibodies can also be found on the datasheet. I have summarised the protocols used and attached the images of the results for your consideration.

Anti-Adiponectin Receptor 2 antibody (ab77612)

Human mesothelioma cell line (ATCC: MSTO-211H), unfixed, were incubated with ab77612 in a dilution of 1/100 in 2% FCS/PBS for 2 hours. Detection was then performed using a donkey anti-goat IgG (H+L) Alexa Fluor® 488 antibody at a dilution of 1/200. The results obtained are attached to this email.

Anti-Adiponectin Receptor 1 antibody [EPR6626] (ab126611)

HepG2 cells stained with ab126611 (red line in histogram attached to this email). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab126611, 1/100 dilution) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-rabbit IgG (H+L) (https://www.abcam.com/ab96899.html) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was rabbit IgG (monoclonal) ( 1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.

Both of these antibodies should work in the experiment you are hoping to perform and you would be covered by the Abpromise guarantee (for more information please follow link below). Should you encounter any problems please do let us know. The dilutions specified are only recommended starting points, for your particular experiment you are likely to need to optimise further in order to obtain the best results.


I hope this information has been of help. If you have any further questions please do not hesitate to ask.

Until then, I wish you all the best with your research.

Thank you for taking time to complete our questionnaire. I am sorry to hear that this antibody is not providing satisfactory results. The details provided will enable us to investigate this case and will provide us with vital information for monitoring product quality. Having reviewed this case, I would like to clarify a few things. Has the protein been sucessfully transfered to the membrane (can be checked by Poncau staining). Also, is there any reason why non-reducing conditions are being used? We would typically recommend using 10 mM fresh DTT or 5% 2-mecaptoethanol in the loading buffer to ensure the disulphide bonds in the protein are fully reduced.  Additionally I would offer some suggestions to help optimise the results from ab77612. As you have noticed, the Western blot presented on the datasheet was performed using 10 µg of HepG2 whole cell lysate and your experiment should therefore show the band expected. Indeed there appears to be a faint band at the expected size (44kDa).  Adiponectin receptor 2 has seven transmembrane hydrophobic domains, expressed at very low levels in most tissues. In order to perform a successful western with such a protein we recommend making cell membrane preparation (as you have been doing) and a then loading 100ug of solubilised membrane protein per lane. It may be worth adding 4M urea to the loading buffer to improve the denaturation and running of the protein in the SDS-gel. I would also recommend to separate proteins on SDS-PAGE gels at 15-20mA constant current when 100-150ug of protein is loaded in each lane to ensure clear separation. SDG-PAGE can be run overnight at 5-7mA constant current and next day in the morning the current should be increased to 20mA until the dye front reaches the bottom of the gel. This will tighten the bands in the gel. Additonally, when transferring hydrophobic integral cell membrane proteins Tris-Glycine buffer containing 0.1% SDS and 10-20% methanol should be used to facilitate transfer of proteins that have 7 hydrophobic domains. I would also try using a different blocking agent such as 3% BSA, with 0.1% Tween for 1 hour at room temperature. It would also be worth removing the blocking reagent from the primary and secondary antibody diluents and trying incubation at both at 4°C overnight as you have been doing and for 2 hours at room temetrature with aggitation.  Hopefully these suggestions will improve the results. However, if you continue to have problems, please do let me know. In the event that a product is not functioning in the species and applications cited on the product datasheet (and the problem has been reported within 6 months of purchase), we would be pleased to provide a free of charge replacement, credit note, or refund. I hope this information is helpful, and I thank you for your cooperation.
