Serum Glycoproteins

[Ian McFarlane]

Does anyone know of a quick and ideally easy way to purify sialoglycoproteins 
from serum. Is their an ion exchange method eg DEAE or a precipitation method, 
I seem to remember reading something about tungstante or vanadate or 
something. Basically what I am trying to achieve is removal of serum albumin 
friom the serum so I can look at the sialoglycoproteins by themselves.
