I have produced a recombinant protein in the yeast Pichia pastoris that is
partially glycosylated with O-liked sugar (there are no N-linked sites in the
protein). I wish to seperate the glycosylated form the unglycosylated protein.
I have tried using ConA-Sepharose (Pharmacia) and Glycine-Max (Sigma) without
success (neither seemed to bind the glycoprotein). The ConA came with
instructions, but I have not been able to dig out any protocol for using the
Glucine-Max and Sigma were not forthcoming.
Has anyone has any experience in using these lectins, or knowledge of any other
techniques that might be of use, I would like to hear from you.
Please reply to my email address as I don't regularly read this newsgroup.
Apologies also to those who frequent the protein-analysis newsgroup as this
message was posted there first, before I became aware of this more appropriate
