Dear Jim,
I know I sound niave, but what would happen if you applied schiff reagent to
the section (No Oxidation Step), gave it a good rinse in 0.5% Sodium
Metabisulphite (Fresh) and then examined it. Wouldn't work would it, because
no sugar, mucin or glycogen necessarily at site, and if was incorporated in
solution before application of schiff would have to bind to site  and be
insoluble.
Could you use an anti-amylase generated antibody  if there is such a thing?
with a 1-5 glycosidic linkage sugar attached, then the glycogen like
material would be bound to the site and visualise with the schiff reagent.
My suggestion is probably pie in the sky stuff, but who knows?
Regards Mike (Downunder)
