[Mass-spectrometry with ion extraction from solution at atmospheric pressure for peptide mapping].
SIE AP mass spectra of tryptic peptides from the cyclo-GMP phosphodiesterase gamma-subunit and of chymotryptic peptides from the cyanogen bromide fragments of the same subunit exhibit MH+ ions for all theoretically possible smaller peptides. These facts show that SIE AP mass spectrometry can be successfully applied to peptide mapping using 1-2 nmoles of the compound.
