This poster demonstrates how the Proteograph™ Product Suite workflow, with the label-free DIA mass spectrometry method, provides highly reproducible proteomics data for large-scale plasma proteomics analysis. (i.e., > 19,000 unique peptides, >2,500 unique protein groups covering broadly and deeply in HPPP database, and for both intra- and inter-batch comparison, peptide intensity CVs < 20% and protein group JI >= 0.85.)
