چکیده

Dissociation of disulfide is normally mandatory prior to disulfide peptide sequencing via electrospray ionization collision induced dissociation mass spectrometry (ESI-CID-MS). Herein, a facile method for directly sequencing intact disulfide peptides was proposed. The basic principles involved were electrolyte-enhanced corona discharge in ESI and the following oxidative cleavage reaction.

Radical induced disulfide bond cleavage within peptides via ultraviolet irradiation of an electrospray plume.

Radical induced disulfide bond cleavage in peptides was demonstrated by ultraviolet (UV) radiation of the electrospray ionization (ESI) plume using a low pressure mercury (LP-Hg) lamp. Tandem mass spectrometry and accurate mass measurements confirmed that the primary reaction products were due to disulfide bond cleavage to form thiol (-SH) and sulfinyl radical (-SO˙). Mechanistic studies showed...

Cross-Linking Electrochemical Mass Spectrometry for Probing Protein Three-Dimensional Structures

Chemical cross-linking combined with mass spectrometry (MS) is powerful to provide protein three-dimensional structure information but difficulties in identifying cross-linked peptides and elucidating their structures limit its usefulness. To tackle these challenges, this study presents a novel cross-linking MS in conjunction with electrochemistry using disulfide-bond-containing dithiobis[succi...

A selective and sensitive liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed for the determination of berberine, palmatine and jatrorrhizine in rat plasma. Target compounds, together with the internal standard (metronidazole), were extracted from rat plasma samples by protein precipitation with acetonitrile-methanol (1:2, v/v). Chromatography was carried out using a ...
