Re: cresyl violet on emulsion dipped slides
|From:||"L. Gibbs" <firstname.lastname@example.org>|
I don't have any great advice on how to get a better Cresyl on
the emulsion dipped slides; but, I do know the emulsion will
slough off in the Cresyl and give the Cresyl stain a short
life. When I have had to stain emulsion-dipped slides I kept a
separate Cresyl for that purpose. I would not use the same Cresyl
to stain other slides.
