deglycosylation

[James Fethiere]

Hello all, I am using different endo and exoglycosidases from 
Boeringher to deglycosylate glycoproteins.  I usually put an excess
of enzyme but I would like to know if the is specific amounts of these
enzymes to use.  What i need is a number referring to mg enz/mg of glycoprotein.
Or in some cases U enz./mg protein, although this unit thing is sometime
confusing.

Thank you
