The un-coupled Naphthol salts (from the phosphatase reaction, dissolved in
the lipids of the tissue) degrade and cause  N2 bubbles .
We solved this problem (in the 60ties!)with a post treatment after the
After the reaction, rinse in dist water,
post fix in formalin 1:4 parts water (just dist. water) for 15 min.
(re-usable), Rinse in dist water and post-treat in a solution of 1%
Sulfanilic acid in 10% Acetic acid (re-usable) for 15 min., rinse in dist
water 4x and mount.
(we used at that time glycerin jelly and/or Aquamount)
