You could try dehydrating in acetone (very quick).

Subject: [Histonet] Methyl green going away...
Hi
my boss requires me to counterstain some DAB immunohistochemistry with methyl
green. I use for that purpose the methyl green in aquos solution 0.5% in 4.2
acetate buffer. The problem is that after the washes I dehydrate and the methyl
green becomes extremely faint with the alcohols. My protocol requires long
periods of alcoholic dehydration very graded. Is there any idea on how to save
the methyl green. Can I use an alcoholic solution?
Thank you very much.
Alonso
