Dear Michelle   I take it that you have unfixed cryostat sections If i
were you I would try to fix them in 4% Paraformaldehyde try about 30mins
to start with. Dehydrate ,defat in xylene then section down to water,
stain in cresyl( my recipe for this is a 0.1% soln cresylviolet in
5%acetic acid then pHto 3.5 with sodium acetate) for about 2mins then wash
well in water and differenciate in ascending alcohols,clear and mount.If
differenciation is a problem you can use a weak acid alcohol.Hope this
p.s  the pH of stain is fairly critical
