  • Function
    Important adipokine involved in the control of fat metabolism and insulin sensitivity, with direct anti-diabetic, anti-atherogenic and anti-inflammatory activities. Stimulates AMPK phosphorylation and activation in the liver and the skeletal muscle, enhancing glucose utilization and fatty-acid combustion. Antagonizes TNF-alpha by negatively regulating its expression in various tissues such as liver and macrophages, and also by counteracting its effects. Inhibits endothelial NF-kappa-B signaling through a cAMP-dependent pathway. May play a role in cell growth, angiogenesis and tissue remodeling by binding and sequestering various growth factors with distinct binding affinities, depending on the type of complex, LMW, MMW or HMW.
  • Tissue specificity
    Synthesized exclusively by adipocytes and secreted into plasma.
  • Involvement in disease
    Defects in ADIPOQ are the cause of adiponectin deficiency (ADPND) [MIM:612556]. ADPND results in very low concentrations of plasma adiponectin.
    Genetic variations in ADIPOQ are associated with non-insulin-dependent diabetes mellitus (NIDDM) [MIM:125853]; also known as diabetes mellitus type 2. NIDDM is characterized by an autosomal dominant mode of inheritance, onset during adulthood and insulin resistance.
  • Sequence similarities
    Contains 1 C1q domain.
    Contains 1 collagen-like domain.
  • Domain
    The C1q domain is commonly called the globular domain.
  • Post-translational
    Hydroxylated Lys-33 was not identified in PubMed:16497731, probably due to poor representation of the N-terminal peptide in mass fingerprinting.
    HMW complexes are more extensively glycosylated than smaller oligomers. Hydroxylation and glycosylation of the lysine residues within the collagene-like domain of adiponectin seem to be critically involved in regulating the formation and/or secretion of HMW complexes and consequently contribute to the insulin-sensitizing activity of adiponectin in hepatocytes.
    O-glycosylated. Not N-glycosylated. O-linked glycans on hydroxylysines consist of Glc-Gal disaccharides bound to the oxygen atom of post-translationally added hydroxyl groups. Sialylated to varying degrees depending on tissue. Thr-22 appears to be the major site of sialylation. Higher sialylation found in SGBS adipocytes than in HEK fibroblasts. Sialylation is not required neither for heterodimerization nor for secretion. Not sialylated on the glycosylated hydroxylysines. Desialylated forms are rapidly cleared from the circulation.

rift reply. Please see below for more details:

1. Please confirm the order number and date of purchase for this vial? The order number you have kindly provided refers to an order placed in February this year. However, you first contacted us in December. What was the order number for the original vial that did not work? Have you ordered the antibody twice and the results have been unsatisfactory from both vials? Or did you get good results from the first vial before ordering the second vial?
Thank you for your clarification of the circumstances.

Sorry about the confusion. We ordered two lot of the same antibody to try (one ordered in November, one in February). So far we have tried the lot ordered in November (GR59826-2) for many times, but it is still not working nicely as expected. My colleague will try the lot we ordered in February soon.

2. I can suggest it would be beneficial to consider including a no primary control to assess if the secondary antibody is binding non specifically. Has the current vial of secondary antibody been used successfully with other primary antibodies? Have you tried a different secondary antibody?

Although a no primary control was not tested, the secondary antibody we used always give nice bands with other primary antibodies. Please see the attached image 1.

3. Could you confirm the sample has been reduced and denatured in sample buffer containing SDS and mercaptoethanol?

We always use NuPAGE Reducing Agent (containing 500 mM DTT) with 10 min boiling at 100C for reducing conditions. This is working well with other antibodies. Please also see the attached image 1.

4. Has the quality of the sample been assessed using a loading control?

Beta-actin was used as a loading control. Please see image 2 for reference.

Thank you very much indeed.

Best regards,

Thank you for contacting us yesterday in regards to the anti-Adiponectin antibody (ab25891).

As requested, I have attached the IHC protocol used with this antibody. Sepcifically:

Sodium citrate buffer(pH 5.5) was used to perform antigen retrieval (using a microwave to heat the buffer).

5% BSA solution was used to block, incubating the buffer with the tissueovernight at 4°C.

10 µg/mL primary antibody was incubated with the tissue in 1% BSA for 1 hour at room temperature.

I would just like to say however that the conditions may need to be optimised to obtain the best staining for your tissue preparation.

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

Thank you for getting back to me with your progress in using the anti-Adiponectin antibody (ab25891).

I am sorry that the use of the new lot has not improved the results sufficiently. Having had a look at the results achieved compared to those initially produced using the antibody purchased in November there has been a marked improvement. Whereas before you had been seeing quite high background from 50 to 100 kDa as well as the expected band at ˜26 kDa, the results now only show minimal background at 50 kDa as well as the expected band (within the LNCap sample). This improvement is probably due to using the milk as the blocking agent instead of the BSA.

It is quite possible that these results can further be improved on by optimising the amount of sample loaded on the gel, the dilution of the secondary antibody and the conditions used to incubate the membrane with the primary antibody. However, I can understand that you have already invested quite a bit of time in optimising this antibody and would thereforebe happy to arrange for a replacement anti-adinonectin antibody to be sent to you(such as https://www.abcam.com/Adiponectin-antibody-19F1-ab22554.html)or any other antibody from our catalogue. Alternatively I can arrange for acredit note to be issued.

Please let me know how you would like to proceed.

I now have some more information to share with you in regards to the anti-Adiponectin antibody (ab25891) you are currently using.In performing the western blot presented on the datasheet of this product we used the following protocol:
1. The primary antibody was used at a concentration of 1 ug/mL
2. We used 5% non-fat dry milk in TBS and block overnight at 4°C.
3. Both the primary and secondary antibodies are diluted in the blocking buffer with the primary being incubated with the membrane overnight at 4°C and the secondary for one hour at room temperature.
I hope this information has been of help. Please do let me know if you have been having any difficulty in using the antibody.
Otherwise, I wish you all the best with your research.

Thank you for contacting us yesterday.

I have looked into what protocol has been used to perform Western blotting with this antibody previously. I do not have the information of how we have used this antibody in this procedure directly to hand but have sought this information from the lab so I hope I will be able to share this with you soon.

The antibodyhas also been used in two publications:

Matushansky I et al. A developmental model of sarcomagenesis defines a differentiation-based classification for liposarcomas. Am J Pathol 172:1069-80 (2008). WB; Human. PubMed: 18310505

Rogers PM et al. Metabolically favorable remodeling of human adipose tissue by human adenovirus type 36. Diabetes 57:2321-31 (2008). WB; Human. PubMed: 18599527

The former does not make any mention ofwhat conditions were usedin the Western blot but the latter doesstate that a 3%BSA blocking solution was used.

Do you have the results back from the blot which youtried yesterday? How did it look?

I will get back to you as soon as I have further information to share in regards to how the Western blot presented on the datasheet of this antibody. I am sorry for the delay and any inconvenience thisis causing you.
