Hi Brett,
at my previous job we did IHC staining for phospho-Histone H3 (ser10) using the Cell Signaling rabbit monoclonal antibody CS9701 in FFPE tissue, and it worked beautifully. It was on human origin tissue, don't remember cross-reactivity in other species but Cell Signaling mentions it reacts with many others. 
Good luck

Jean-Martin

I am looking for an antibody for labeling FFPE sections of mitotic cells
that are only in M-phase. Found one article in J Histo Cyto using clone
HTA28-phospho-Histone H3(Ser 28) that looked pretty good, but the
Authors produced their own antibody.

The commercial suppliers I have been able to locate do not indicate IHC
as a suitable application for their products.

Anyone had experience with this??  

Or can you recommend another M-phase specific antibody?

Many thanks,
Brett
