Characteristics of the Quartet. A Proteins identified from the Quartet samples. B Cumulative number of proteins identified as a function of experiment numbers. C Gene ontology analysis of cellular component terms (GO-CC). D Average number of proteins identified from different experiments using the single-shot strategy. E Number of proteins identified from different experiments using a deep-coverage strategy. F Number of proteins identified distributed over 11 confidence intervals. The stack column labeled “Total” indicates the global distribution of all proteins identified from the Quartet samples. Right panel: detailed protein identification information within rough confidence intervals: 0–10%, 10–60%, 60–100%, and 100–100%. G Proteins with high quantitative stability distributed into different quantitative orders of magnitude
