Rapid and efficient structural analysis is key to the development of new monoclonal antibodies. We have developed a fast and easy process to obtain mass spectrometry profiles of antibodies from culture supernatant. Treatment of the supernatant with IdeS generates three fragments of 25 kDa that can be analyzed by liquid chromatography–mass spectrometry time-of-flight (LC–MS TOF) in one run: LC, Fd,...
