Formation of [b(n) + 17 + Ag]+ product ions from Ag+ cationized native and acetylated peptides
Anbalagan, Victor; Perera, B. A.; Silva, A. T. M.; Gallardo, A. L.; Barber, M.; Barr, J. M.; Terkarli, S. M.; Talaty, Erach R.; Van Stipdonk, Michael J. (John Wiley and Sons, 2002-09-01)We compared the tandem mass spectra of a range of native and acetylated Ag(+) cationized peptides to determine the influence of the derivatization step on the abundance of the [b(n) + 17 + Ag](+) product ions. Using ... -
Influence of a ring substituent on the tendency to form H(2)O adducts to Ag(+) complexes with phenylalanine analogues in an ion trap mass spectrometer
Perera, B. A.; Gallardo, A. L.; Barr, J. M.; Tekarli, S. M.; Anbalagan, Victor; Talaty, Erach R.; Van Stipdonk, Michael J. (John Wiley and Sons, 2002-04-01)In a previous report we showed that certain binary Ag(+)-amino acid complexes formed adduct ions by the attachment of a single water and methanol molecule when stored in an ion trap mass spectrometer: complexes with aliphatic ... -
Multi-stage tandem mass spectrometry of metal cationized leucine enkephalin and leucine enkephalin amide
Barr, J. M.; Van Stipdonk, Michael J. (John Wiley and Sons, 2002-01-01)We have examined the multi-stage collision induced dissociation (CID) of metal cationized leucine enkephalin, leucine enkephalin amide, and the N-acetylated versions of the peptides using ion trap mass spectrometry. In ...
