Oxidative Folding of Conotoxins in Immobilized Systems

We tested two alternative oxidation strategies to produce conotoxins α-GI and μ-PIIIA. The peptides were either reversibly immobilized on a solid support and then oxidized, or the immobilized disulfide reagent (CLEAR-OX™) was used to oxidize the peptides. Both strategies appeared more efficient at higher peptide concentrations, consistent with pseudo-dilution effects.
