Supplementary Figure 2: 4 Protein Mix.
Spectra of a synthetic mixture of intact proteins created by tradition ensemble ion collection plotted in m/z space (a), or via the I2MS process (b). The table in panel (c) lists the known proteins in the mixture along with their masses and corresponding figures of merit determined from the I2MS spectrum in panel (b). The number assigned to each protein in the table correspond to the labeled features in the m/z spectrum and corresponding I2MS spectrum in panels (a) and (b), respectively.
