I don't know how much mileage you'd get out of it with your protein, but I was able to get very efficient disulfide linkage at the dimerization interface of my protein by dropping the salt to nearly nothing and running lots of buffer over it after immobilization on a cation exchange column (dur

In the literature, you can find examples of air oxidation, oxidized glutathione (alone), mixture of reduced and oxidized glutathione, and hydrogen peroxide. The correct concentrations have to be found empirically. We are just now mushing through this with an engineered disulfide variant. Air ox
