A. Jones et al., ISOLATION AND CHARACTERIZATION OF CONOPEPTIDES BY HIGH-PERFORMANCE LIQUID-CHROMATOGRAPHY COMBINED WITH MASS-SPECTROMETRY AND TANDEM MASS-SPECTROMETRY, Rapid communications in mass spectrometry, 10(1), 1996, pp. 138-143
The sensitivity of mass spectrometry combined with the separatory powe
r of high-performance liquid chromatography was used to investigate th
e venom of individual cone shells, This analysis has revealed that con
e venoms contain a complex mixture of peptides which vary quantitative
ly and qualitatively both between and within species, A differential a
lkylation procedure followed by tandem mass spectrometric analysis can
be used to determine the disulfide bond connectivity in these small,
cysteine-rich peptides.
