Succinyl wheat germ

[Friedrich Altmann]

Dear Irina, wheat germ agglutinin as probably all the other 
"GlcNAc-specific" lectins does not bind very well to structures 
terminating in GlcNAcß1-2Man. WGA rather binds to chito-oligosaccharides 
which are however not usually contained in glycoproteins. We have also 
tried Bandeiraea simplicifolia II with ovalbumin and other 
GlcNAc-Man-containing glycoproteins - with very little success !
So your problem might be one of lectin binding for which Pierce is not 
responsible. 
Kind regards, Fritz Altmann
