  • ab81443 staining Fibromodulin in Mouse aorta tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with 10% Formalin and blocked with 10% serum for 30 minutes at 22°C; antigen retrieval was by heat mediation in a citrate buffer. Samples were incubated with primary antibody (1/200 in 10% Normal Goat serum) for 16 hours at 4°C. A Biotin-conjugated Goat anti-rabbit IgG polyclonal (1/375) was used as the secondary antibody.

  • ICC/IF image of ab81443 stained HeLa 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 (ab81443, 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.

Thank you for that information.
As discussed, I can arrange for the ab81443 of a different lot number to be sent to you. However I will just need to check your order details for the original vial of ab81443. I have the following information, does this match your order and is this the delivery address you would like the antibody sent to?
Order number xxxx Purchase order number xxxxxx
Delivery address:
Once I have this confirmation I will arrange for the shipment. I look forward to receiving your reply.

Thank you for your reply.
This has made understanding the problems you have encountered and what may be contributing to them easier to understand. I cannot be sure what is causing this problem, but from what you have described, I would suggest it may either be the fixation or the antigen retrieval currently used.
If the tissue is over fixed, this can leads to the antibody not being able to recognise the protein. Alternatively, non-optimal antigen retrieval can also lead to the epitope not being exposed for detection. Therefore, can i ask the following:
1. How was the tissue harvested and fixed?
2. When optimising the antigen retrieval, which methods were used? You have mentioned the buffers but the method of heating (microwave, pressure cooker) and for what times were the incubations tried?
I cannot rule out either that the antibody itself has become inactivated for some reason. I understand that you have used a lot of time and effort in trying to optimise the results and I would have expected there to be some staining from the information you have shared with me. I am sorry to for the inconvenience this problem is causing you.
If you would like, I can send you a new vial from a different lot of ab81443 free of charge to try? Alternatively, I can send you an alternative antibody altogether. Unfortunately, we do not currently have any other anti-Fibromodulin antibodies available which have been shown to work in IHC but any other antibody from our catalogue. Or I can understand if you would prefer a refund or credit note to be issue.
I look forward to receiving your reply.

Thank you for contacting us and raising your concerns in regards to the anti-Fibromodulin antibody (ab81443).
I am sorry to hear you are experiencing difficulties with this product. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.
It seems from the details you have provided that the antibody should have worked with your samples. In order to try and understand more fully why this has not been the case, would you mind providing me with a few more details of the experiment being carried out? To this end I have attached a questionnaire.
Also, you mentioned you have been using another anti-Fibromodulin antibody with better results. Could you let me know which antibody this is (supplier and catalogue number)?
Once I have received the completed questionnaire, I will look at the protocol and see if there are any suggestions I can make that may improve the results. This information will also allow us to investigate this case internally and initiate additional testing where necessary.
If the product was purchased in the last six months and is being used according to our Abpromise, we would be happy to replace or refund the antibody.
I look forward to receiving your reply.
