Published: July 2017

Very highly charged proteins, so-called "supercharged" ions, can lose (excess) protons to background gases like N . It is remarkable that such extremely acidic species can be generated in electrospray ionization, in the presence of not just N but also much higher-basicity solvents. What mechanism(s) can explain such high charging, and what is the ultimate limit?
