    摘要: The present invention relates in part to methods for determining bonding patterns in disulfide-linked peptides containing closely-spaced cysteine residues. Through N-terminal sequencing chemistry coupled with facile liquid chromatography and mass spectrometric analysis of the cleavage products, one can assign connectivity to specific cysteine pairs. A particular advantage of this method is maintenance of disulfide integrity during the process.
