Are you soaking your blocks in dilute ammonium hydroxide before sectioning? Soaking too long will affect stain quality.

The main complaint is no differentiation between the nucleus and cytoplasm. We are using Richard-Allan hematoxylin ,eosin,clarifier and bluing. We tried surgipath, changing times, pH the H2O and any other thing we could think of, but the problem remains. Does anyone have a suggestion?
