Accurately quantifying the proteome remains challenging for large sample series and longitudinal experiments. We report a data-independent acquisition method, Scanning SWATH, that accelerates the mass spectrometric duty cycles, yielding quantitative proteomes in combination with short gradients and high-flow (800 µL/min) chromatography. Exploiting a continuous movement of the precursor isolation window to assign precursor masses to the MS/MS fragment traces, Scanning SWATH increases precursor identifications by ~70% compared to conventional DIA methods on 0.5-5 minute chromatographic gradients. We demonstrate the application of ultra-fast proteomics in drug mode-of-action screening and plasma proteomics. Scanning SWATH proteomes capture the mode-of-action of fungistatic azoles and statins. Moreover, we confirm 43 and identify 11 new plasma proteome biomarkers of COVID-19 severity, advancing patient classification and biomarker discovery. Thus, our results demonstrate a substantial acceleration and increased depth in fast proteomic experiments that facilitate proteomic drug screens and clinical studies.
