Proteomics (proteomics-v1 release)

Real, published proteomics datasets used by the ov.protein tutorials:

Asset Source Description
protein_pxd000022.h5ad ProteomeXchange PXD000022 (via Bioconductor imputeLCMD) Label-free LC-MS/MS, 660 proteins × 6 samples, 2 groups (MB/MT)
protein_pxd000279.h5ad ProteomeXchange PXD000279 (via MaxQuant; the DEqMS-vignette benchmark) Label-free LC-MS/MS spike-in, 6507 proteins × 6 samples, 2 groups (HeLa+E.coli 3:1), real peptide counts + species ground truth
protein_pxd000438.h5ad ProteomeXchange PXD000438 (via imputeLCMD) Label-free LC-MS/MS, 3709 proteins × 12 samples, 4 groups, ~41% left-censored missing
protein_msstats_dda.csv.gz MSstats DDARawData Controlled spike-in label-free DDA, feature-level (MSstats long format)
protein_msstats_dia.csv.gz MSstats DIARawData Label-free DIA, S. Pyogenes group comparison (MSstats long format)
protein_olink_npx.csv.gz OlinkAnalyze npx_data1 Olink Explore NPX, long format, real bridging study
