Synthesis of 13C7-labeled iodoacetanilide and application to quantitative analysis of peptides and a protein by isotope differential mass spectrometry
摘要:
C-13(7)-Labeled iodoacetanilide has been synthesized for specific labeling of sulfhydryl groups of cysteine residues and has been successfully applied to quantitative analysis of peptides and a commercial protein in combination with C-13-unlabeled iodoacetanilide and a MALDI mass spectrometer. Subsequent tandem mass spectrum analysis revealed that C-13(7)-labeled iodoacetanilide remained intact during the collision-induced dissociation ( CID) conditions. (C) 2009 Elsevier Ltd.
