ron based analysis under conditions whereby peptide backbone cleavages were
observed. Precedence would have indicated that this interchain disulfide bond
should not have been so stable (Crimmins et al. 1995; Hemling et al. 1996; Patterson and Katta 1994; Zhou et al. 1993).
Data derived with PMP derivatives of oligo saccharides suggests that MALDIPSD of these derivatives will be of use in characterizing protein glycans.
The data reviewed herein indicate that the utility of MALDI-PSD should be
assessed in a problem specific context and precedents or dogma should not rule
out consideration of the use of PSD in particular circumstances.
