Alcian Blue at pH 2.5 or 1.0, precceded by digestion with specific 
enzymes, will work for formalin-fixed (better is formalin-alcohol-acetic 
acid) tissues.
There is also the "critical electrolyte concentration" methods with 
Alcian Blue.
Some lectin methods (see Vector Labs website) will demo specific amino 
sugars of the GAG.
