  • De-paraffinized and dehydrated sections were treated in a microwave oven at low power for 10 min in 0.01 M sodium citrate buffer (pH 6.0) to retrieve antigen, and inactivated endogenous peroxidase using 3% hydrogen peroxide in methanol for 10 min, and blocked with blocking solution for 1 hour at room temperature. Sections were then incubated with 1∶20 dilution of mouse monoclonal antibody to 8-Hydroxy-2'-deoxyguanosine (ab48508) overnight at 4°C. For detection, a biotinylated anti-mouse and HRP-labeled Streptavidin, and staining with DAB was used.

    Immunohistochemical staining of nitrotyrosine (A) and 8-hydroxy-2′-deoxyguanosine (B) was performed on 5 rats randomly chosen from each group (ND: chow diet group, HFD: High fat diet, HFD-QH: High fat diet treated with Qing Huo Yi Hao" (QHYH)). An islet is encircled in each quandrant. Black arrows point to islets of Langerhans (Original magnification ×200). Percentage of immunohistochemial positive staining area in islet out of the area of corresponding islet (C, D) was presented. Values and bars represent means±SEM. * and ** denote P<0.05 and P<0.001 versus group ND.

  • ab48508 staining 8-Hydroxy-2'-deoxyguanosine in human colon tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with paraformaldehyde and antigen retrieval was by heat mediation in a TE buffer. Samples were incubated with primary antibody (1/50) for 30 mins at 20°C. A HRP-conjugated Goat anti-mouse IgG was used as the secondary antibody.

Thank you for your enquiry regarding ab48508.

Would you be so kind to confirm if the tube has been centrifuged before opening the lid? It would help me if you could specify how much volume of the liquid was in the vial?

Thank you for your understanding and co-operation in this matter. I look forward to hearing from you and hope to solve this problem as soon as possible.

Thank you for contacting us.

I can recommend the antibody ab48508 against 8-hydroxy-2'-deoxyguanosine. This antibody has been tested in immunohistochemistry on paraffin embedded tissue sections (IHC-P). (or use the following:

Alternatively, we do have also the ab264842 which has been tested in IHC-P. (or use the following:

All these antibodies will also work on mouse tissue. As they are however mouse antibodies, you must be careful not to introduce background by the detection with the secondary antibody. To avoid such a problem, I can recommend you to block endogenous mouse immunoglobulins on the tissue slides. This can be done with our MOM kit for example (ab127055). (or use the following:

I hope this information is helpful to you. Please do not hesitate to contact us if you need any more advice or information.

Thank you for your enquiry.

Both these antibodies are designed to detect a specific DNA modification which is a species-independent reactivity. So yes, both antibodies are suitable for use in rat.

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

I have heard back about ab48508.
The antibody ab48508 (anti 8-OHdG monoclonal antibody) is specific for
8-Hydroxy-2'-deoxyguanosine(8-OHdG). 8-Hydroxyguanosine (8OHG) demonstrate
minimal crossreactivity (less than 1%).
I will get back to you as soon as I hear back about the other antibody.
Once again thank you for your patience.
