  • IHC image of alpha tubulin staining in human colon formalin fixed paraffin embedded tissue section*. The section was pre-treated using pressure cooker heat mediated antigen retrieval with sodium citrate buffer (pH6) for 30mins. The section was incubated with ab64332, 5µg/ml overnight at +4°C. An HRP-conjugated secondary (ab97057, 1/200 dilution) was used for 1hr at room temperature. The section was counterstained with haematoxylin and mounted with DPX.

Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections)
The secondary ab works well. Based on my experience for IHC the dilution factor requires optimization based on the tissue and antigen retrieval method used.
In the attached picture you can see F480 used as primary antibody and the secondary Goat Anti-Rat IgG H&L ab 97057 used at the concentration of 1:200.
The dilution 1:500 works well too.

The price of this antibody is good based on the amount provided with the shipment.
I used this Antibody at the dilution 1:10000 and it worked fine in my WB.
In the attached picture ab6640 was used as primary antbody in tissue lysates from human macrophages and ab 97057 was used as secondary antibody. The secondary and primary antibodies were diluted in 2% Milk in PBS.

We are using an 2 years old vial of this antibody, it still works well.

Western blot
Antibody recognizes the Rat antibody specifically. I analyzed an HA tagged protein (0.4 OD cells equivalent) and used the anti-Rat HA antibody that was purchased from Roche and this secondary antibody ab97057 was used as secondary. I used 1:10K dilution of the antibody and incubated for 1hr at room temperature. Nitrocellulose membrane was used for blotting. On the blot the lane 1, 2, 3 were three individual clones picked after transformation. The protein of the right molecular weight was observed. (70kD).

Lane 1 is wild-type mouse ES cells expressing E-cadherin. Lane 2 is an Ecad-/- mES cell line. DECMA-1 primary antibody used (not Abcam). Secondary used at 1:5000 for 1 hour. Use of secondary at higher concentration of 1:2000 results in background staining.

Thank you for your reply.

Any anti rat IgG antibody tested in IHC-P should be suitable for your experiments and would be covered by the guarantee. I can suggest you may like to try the following. I can recommend to review the online datasheet for further information.

ab98425 Goat polyclonal Secondary Antibody to Rat IgG - H+L (HRP), pre-adsorbed
HRP conjugated
Tested in: ELISA, ICC, IHC-P, WB
https://www.abcam.com/index.html?datasheet=98425 (or use the following: https://www.abcam.com/index.html?datasheet=98425).

I hope this will be helpful. I look forward to hearing from you with details of how you would like to proceed.

Thank you for your message.

It is indeed disappointing that the results are not yet satisfactory, it is regrettably and I appreciate your concerns.

In this case, I would suggest it would be most beneficial to try a different secondary for detection of the rat IgG2a primary. For example, the following page provides the search results for HRP conjguated anti rat IgG antibodies tested in IHC-P:


The reason is that by using both a secondary and tertiary antibody, there are more variables added into the experiment which means there is more opportunity for it to go wrong, and it will be much more difficult to troubleshoot. It is also more expensive.

The decision is yours. I am happy to provide a free of charge vial of an HRP conjugated anti rat IgG secondary, and this is what I would advise at this stage. Alternatively, I can provide a free of charge alternative replacement of ab6703. I would like to reassure you that any replacement provided would be covered by the 6 month guarantee.

I hope this will be helpful to you. I look forward to hearing from you with details of how you would like to proceed.
