glycosylated protein on SDS gel

[dslomczy at mailbox.syr.edu]

Yes glycosylated proteins will act strangely.  There was two papers out in
Biochemistry by Leach, Colwan, and Fish about measuring molecular mass by
SDS-electrophoresis and other methods.  There conclusions were the glycoproteins bind
enough SDS (the glycosylation doesnot bind SDS), so the charge to mass ratio is off.  One
can expect between -50 to +50% change with glycosylated proteins.  I hope this helps.
