Top-down characterization of proteins via tandem mass spectrometry (MS/MS) can be challenging due to the presence of multiple disulfide bond linkages; which significantly inhibit the backbone cleavage efficiency for the formation of structurally informative fragment ions. In this study, we present a strategy of pairing a solution-phase photoinitiating system with dipolar direct current induced collisional activation of electron transfer products (ET-DDC) of proteins for a top-down MS/MS approach ...[more]
