ConA - glycoproteins - ovalbumin

	Hi all!

	We're trying to purify a complex of glycoproteins from hen 
oviduct. We're following a procedure which purified the same protein from 
dog pancrease. However, in using a ConA sepharose column to separate the 
glycoproteins, it seems that with the chicken oviduct, all that gets 
bound and eluted is ovalbumin.  Of course, this is a glycoprotein, and is 
in great abundance in the chicken, but not in the dog pancreas at all. 
Does anyone have any ideas on how to circumvent this purification 
obstacle? Could we get rid of the ovalbumin in any way?
