Basic solutions of myoglobin, beta-lactoglobulin, pepsin and ubiquitin
have been examined by means of electrospray mass spectrometry in the
negative ion detection mode. The distribution of protein ions in the m
ass spectra was found to correlate well with the distribution of prote
in species in solution calculated from published titration data. These
results lend further credibility to an earlier proposed aqueous solut
ion acid/base equilibrium model, which relates the ''bell-shape'' ion
distribution observed in the electrospray mass spectrometry of protein
s to the distribution of protein ions in solution.
