Thank you for your patience.

I confirmed with the lab and am happy to forward their confirmation that ab98754 will detect both the (Fab) and the (Fab’)2 fragments of mouse IgG.

Please note that ab98754 itself is also a (Fab')2 fragment and therefore does not have an Fc part.If this is not suitable for the experiments that are planned, I am currently waiting on more information on ab139582. If the lab confirms that this antibody is also binding to both (Fab') and (Fab')2, I will let you know.

I hope this information is helpful and wish you good luck with your experiments.

Thank you for this information.

I have noted that this primary/secondary antibody combination has been used and reviewed by another customer. Their Abreview includes a detailed protocol which you may wish to review. This review is at:https://www.abcam.com/index.html?datasheet=33483&tab=abreviews&intabreviewid=14724

It may be in your case that much of the background is caused by secondary antibody binding to
endogenous mouse IgG in the tissue being stained, and to Fc receptors on B cells, plasma cells and macrophages. As such it may be valuable to use some of the staining procedures for mouse on mouse staining. Blocking endogenous IgG may be done by incubating the sections with an unconjugated Fab fragment likeGoat F (ab')2 polyclonal Secondary Antibody to Mouse IgG - (Fab')2, pre-adsorbed (ab98754),after the normal blocking step.More details may be found at this link:

I hope that this information is helpful. Please let me know if you have any questions or there are other ways that Abcam may help you meet your research goals.

Thank you for contacting us.

Indeed, a mouse-on mouse staining can be quite tricky; however, it is not impossible. The background will depend on the fixation method ( perfusion fixed tissue vs. normally fixed tissue), on the tissue itself ( eg. kidneys vs. bone) and the experimental settings.

One way to make sure to decrease or to completelyerase the background is to block the endogenous mouse IgG with a non- conjugated secondary antibody before you incubate with your target antibody. I would suggest to use a Fab or F(ab)2 fragment antibody in this case as they will bound in a higher density than whole IgG antibodies.
