Hi Brandon
Was the over fixation done in formalin? If so then trypsinize the sections
to brake up the methylene bridges due to formalin overfixation. That should
eliminate the blue haze that you see. Then post fix in a bouins solution 60
degrees celsius for one hour. Bouins seems to enhence the analine blue
stain. Otherwise time all the other stains as you would normally.
Depending on the tissue you may have to try several different times in
trypsin before you get what you want.
Your question..

Good luck
