Hi,

I'm working on sulfated glycopeptides.
I've a problem to characterize one of them.
The problem is the small quantity of my product: I can't
do TLC and I can't detect it by ElectroSprayMass Spectrometry
neither by MaldiTOF Mass Spectrometry because I think some degradations occur
(due to the Mass conditions).
I've not tried the FAB-Mass for the moment.

How can I characterize it?

Some sugars are more sensitive to conditions used
to perform a Maldi Mass Spectrum than other sugars?

Thanks.
