Hello All,
 Whenever we bleach a slide prior to IHC staining, the end result is
sub-optimal.    Our protocol is to use 0.5% potassium permanganate and
then oxalic acid for the bleach then to proceed with the automated IHC
stain using Ventana's DAB I-View Kit.   Most of the tissue comes off the
slide and the remaining tissue has poor morphology.  Does anyone have
good advice for me?  
Thanks in advance,
