[Histonet] Alcian Blue problem

It also stains ceramic sinks pretty well! The dye cations
are supposed to stick to the silicate anions of the glass
or pot. The slide adhesive paper is:

Archimbaud E, Islam A, Preisler HD (1986) Alcian blue 
method for attaching glycol methacrylate sections to 
glass slides. Stain Technology 61: 121-123.

To obtain a positively charged surface this way you'd 
have to stain the slides immediately before using, and
wash in something a bit acidic. Anything as basic as
water removes the pendant cationic groups from bound
alcian blue, leaving behind uncharged and completely
insoluble copper phthalocyanine. I don't have that
issue of Stain Technology to hand, so cannot check up
on the method.
