Mircoplate assay for carbohydrate

[RAY MCGUIRK (BIOCHEMISTRY) PG]

Dear Glycoscientists,

I am looking for a simple, sensitive and reproducable microplate 
assay for free or bound hexoses and/or sialic acids. I am trying to 
quantify the amount of carbohydrate being removed from a glycoprotein 
with endo- and exo- glycosidase enzymes over time. References would 
be much appreciated.

Thanking you in advance,
