Cysteine residues in polypeptides are not easily identified during automated N-terminal sequence analysis. Reaction of cysteine side chains with 4-vinylpyridine and identification as the pyridylethylated phenylthiohydantion derivative (PE-PTH-Cys) were proposed. However, after this reaction a desalting step is necessary. If
