Dear John,

To address your last question first; Con A will bind to any glycoprotein as 
long as it carries appropriate glycans. The specificity of Con A is to 
alpha-linked mannose residues so it will bind strongly to oligomannose and 
hybrid type glycans. HRP is not a good example. In order to predict what 
'proteins' Con A will bind requires a knowledge of the glycosylation of the 
protein. In a given cell I would expect that many different glycoproteins 
will carry the necessary structures for binding to Con A.   

As to a list of Con A binding glycoproteins, I don't know if one has been 
collated recently. Pharmacia used to keep a bibliography of applications 
for Con A-Sepharose, you could try them. Alternatively, you could look back 
at reviews on lectins for information and as possible sources of 
references. Try Lis & Sharon (1973) Ann.Rev.Biochem. 42, 541-574 or 
Goldstein & Hayes (1978) Adv.Carb.Chem.Biochem. 35, 127-340. Also there's a 
book on lectins "The Lectins. Properties, Functions, and Applications in 
Biology and Medicine." Eds. Liener, Sharon & Golstein, Academic Press, 
(1986).

Good hunting,

David
