(ii) intact folded 5P12-RANTES in which the cyclization of the N-terminal glutamine
residue had occurred and both methionine residues had been oxidized to Met(O) (expected ¼ 7937.7), or (iii) intact folded 5P12-RANTES in which the cyclization of the N-terminal glutamine residue
had occurred and one of the two methionine residues had been oxidized to Met(O2).
