Hi Ray,


I use toulidine blue on glycolmethacrylate and epoxy sections often.  The
routine differs a little, though because the glycol methacrylate sections
are much easier to get to stain.  I remove the stain right after I put it
on the slide, then quick rinse in 3 changes of distilled water, followed
by a 5 second rinse in 70% Ethanol and 1 more rinse in distilled
water.  Let it dry and look at it and if it needs more stain, restain.

Epoxy sections take longer to stain.  I often leave them on the warmer
with a lid over the slide to keep it from drying.
