[Histonet] Glycerin-Gelatine bubble-phenomen

[meyenhmf <@t> umdnj.edu]

Bubbles are caused by desintigration of uncouppled, tissue bound dyes, a
phenomenon described in the 60ties occuring with some enzyme histochemistry
reactions.
A treatment with acidic formalin and sulfanilic acid after the reaction
would reduce/eliminate the bubbling effect.
