Abstract
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.
