[HTML] New ionization tags based on the structure of the 5-azoniaspiro [4.4] nonyl tag for a sensitive peptide sequencing by mass spectrometry

B Setner, Z Szewczuk - Analytical and bioanalytical chemistry, 2018 - Springer

Quaternary ammonium salts (QAS), both linear and bicyclic, are often utilized to improve the
mass spectrometry (MS) analysis of peptides by fixing a permanent positive charge on the
analyzed molecule. However, during collision-induced dissociation (CID) experiments, QAS …
