Thank you for contacting us.

Neither antibody has been tested for reactivity with rabbit CEACAM1, and the epitopes each antibody recognizes have not been mapped, so it is difficult to predict cross-reactivity with rabbit. If I needed to choose one, I would choose ab49510, given the quality of the IHC image and the references. However, rabbit reactivity is not covered by our guarantee.

Please do not hesitate to contact us if you need any more advice or information.

Thank you for your inquiry. I was liaising with the laboratories to find out more about our pan-CEACAM- and CEACAM1-antibodies. Unfortunately, it turned out that we do not have any suitable antibody available: The immunogens of our CEACAM1 antibodies share a sequence homology with dog of 67% at the best. Thus, we would not predict a cross-reactivity for one of these antibodies. The same applies for our pan-CEACAM antibodies: The human CEACAM proteins used as immunogens reveal sequence similarities with the dog ortholog that are below 70%, suggesting that a cross-reactivity of the antibody is rather unlikely. If you have not done yet, I would like to recommend checking the Biocompare website which has an excellent antibody search facility that includes many suppliers. The links are: www.biocompare.com http://www.biocompare.com/ProductCategories/2045/Antibodies.html I am sorry that I could not be more helpful on this occasion and hope this information is nevertheless helpful to you. Please do not hesitate to contact me if you have any further questions in this regard.
