  • IHC image of Hem Oxygensae 1 staining in a section of formalin fixed, paraffin embedded normal human spleen tissue section*, performed on a Leica Bond™ system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab13248, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.


    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.

Thank you for contacting us.

I have checked the details you have kindly provided. I would suggest the following troubleshooting steps;

- Please add cocktail of protease inhibitors in lysates.
- This antibody works perfect in reducing conditions. Please add DTT in sample buffer.
- Try heating the lysates at 100C for 10 minutes.
- Load 20-30ug of lysates.
- Try 5-10 ug/ml of antibody concentration.
- Please make sure the secondary is a anti-mouse antibody.

Please try these steps and let me know the results.

Many thanks for your cooperation. I will look forward to hearing from you soon.

Thank you for calling us and for alerting us to the problem you are experiencing with our product. We take product complaints very seriously, and investigate every product that we feel may not be performing correctly.

As we discussed on the phone, I am attaching our questionnaire so that we can gather further information regarding the samples tested and the protocol used. Once we receive the completed questionnaire, we will look at the protocol and see if there are any suggestions we 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.

Thank you for your email.

We have another kit, the Protein Quantitation Kit (Bradford Assay), ab102535, which may also be of interest to you. Or we also have Bradford reagent available from our catalogue, ab119216 and ab119216 for 500 and 1000 mL respectively. This can be used to set up your own protein quantification assay.

If you have any further questions relating to these products please do not hesitate to let me know.

Thank you for your reply.

Both the rabbit monoclonal ab52947 and the ab13243 have been shown to work well in IHC of paraffin embedded tissue sections. The results achieved can be seenfrom the images presentedon the datasheet of these products. Ab132436 has also been used in the following research article to stain mouse tissue:

Jortay J et al. Local induction of adiponectin reduces lipopolysaccharide-triggered skeletal muscle damage. Endocrinology 151:4840-51 (2010). PubMed: 20702578

Rabbit monoclonals are considered to be very good antibodies as they are specific and consistent like mouse monoclonals but also generally have very high affinity. However, I thought you wanted to use the antibody with rat tissue as well and as the rabbit monoclonal ab52947 has been shown not to react with rat samples this is why I did not suggest it to you.

We do not have either of the two compounds but I would be happy to pass these onto the lab to see if they are able to provide them. Do you know how much you would be interested in purchasing?

I look forward to receiving your reply.

I hope your grant application is going well. We have several antibodies against the targets you have mentioned which may be of interest to you:


I would suggest looking at the rabbit polyclonal https://www.abcam.com/Heme-Oxygenase-1-antibody-ab13243.html. This has been shown to react with human, mouse and rat samples and has been used in ICC, IHC-Paraffin embedded, sELISA and Western blotting to date. We also have a very popular mouse monoclonal https://www.abcam.com/Heme-Oxygenase-1-antibody-HO-1-1-ab13248.htmlwhich has also been used with human, mouse and rat samples as well as in ELISA, Flow Cytometry, ICC,IHC-Frozen sections, and Western blotting. Bit I think you were more interested in antibodies raised in rabbit.


For this target I would suggest having a look at the rabbit polyclonal https://www.abcam.com/COX2--Cyclooxygenase-2-antibody-ab15191.html. This has again been tested with mouse, rat and human samples and has been used in ICC/IF, IHC-Frozen sections, IHC-Parrafin embedded, IP, sELISA and Westernblotting.

We also have the NS-398 compound (COX-2 inhibitor) which is available under the catalogue number https://www.abcam.com/NS-398-ab120295.html.

I am afraid I have not been able to find a similar inhibitor of VEGF. Do you have a particular compound in mind? It may be that I can suggest we start stocking it.

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