Oxford GlycoSystems and Boehringer Mannheim both sell kits for detection of 
glycoproteins, but I've never used them. There's no doubt that Schiff staining 
is NOT the method to use. Also there are a couple of books coming out on 
methods relating to glycosylation. "Glycobiology" one of the Practical 
Approach series is out on 17th Feb. from IRL/OUP (so I'm informed); and the 
Lennarz/Hart edited Methods in Enzymology on similar methods should also be 
coming out. At the moment the older "Carbohydrate Analysis" Practical Approach 
book may have some methodologies of relevance.
