Did he decalcify the tissue?  Most saccular macculi have calcified
otoconia on their surface (in the otoconial membrane).  I have done some
IHC on frozen sections of chinchilla inner ear, but I prefer the
preservation of structure that you get with paraffin.  Can he embed in
paraffin or is the antibody sensitive to it?
