The described comparative, quantitative proteomic approach aims at obtaining insights into the composition of multiprotein complexes under different conditions and is demonstrated by comparing genetically different strains. For quantitative analysis equal volumes of different fractions from a sucrose density gradient are mixed and analyzed by mass spectrometry.
