## Abstract Negative ion ESI mass spectrometry was used to study the gas‐phase stability and dissociation pathways of peptide–DNA complexes. We show that bradykinin and three modified peptides containing the basic residue arginine or lysine form stable interactions with single‐stranded oligonucleot
