Two new technologies have made the study of proteins by mass spectrometry
straightforward. Proteins with molecular masses of up to more than 100 kilodaltons can be
analyzed at picomole sensitivities to give simple mass spectra corresponding to the intact
molecule. This development has allowed unprecedented accuracy in the determination of
the molecular weights of proteins. A number of" case studies" are used to present the
