• The data from version 2 are available at Huffman et al, 2022, version 2

Single-cell proteomics method: pSCoPE

Sample preparation method: nPOP

Model systems: Primary murine bone marrow derived macrophages and a pancreatic ductal adenocarcinoma (PDAC) cell line.

Processed pSCoPE Data RAW pSCoPE Data

pSCoPE data processed to ASCII text matrices

Benchmarking experiments: Figure 1b/e data

• Peptides-raw.csv
  • Peptides x single cells at 1% FDR. The first 2 columns list the corresponding protein identifiers and peptide sequences and each subsequent column corresponds to a single cell. Peptide identification is based on spectra analyzed by MaxQuant.

• Proteins-processed.csv
  • Proteins x single cells at 1% FDR, imputed and batch corrected.

• Cells.csv
  • Annotation x single cells. Each row corresponds to a single cell annotated with relevant metadata, such as, cell type if known, measurements from the isolation of the cell, and derivative quantities, i.e., rRI, CVs, reliability.

Benchmarking experiments: Figure 1c/d data

• Peptides-raw.csv
  • Peptides x single cells at 1% FDR. The first 2 columns list the corresponding protein identifiers and peptide sequences and each subsequent column corresponds to a single cell. Peptide identification is based on spectra analyzed by MaxQuant.

• Proteins-processed.csv
  • Proteins x single cells at 1% FDR, imputed and batch corrected.

• Cells.csv
  • Annotation x single cells. Each row corresponds to a single cell annotated with relevant metadata, such as, cell type if known, measurements from the isolation of the cell, and derivative quantities, i.e., rRI, CVs, reliability.

Bone-marrow-derived macrophage experiments: Figures 2, 3, and 4

• Peptides-raw.csv
  • Peptides x single cells at 1% FDR. The first 2 columns list the corresponding protein identifiers and peptide sequences and each subsequent column corresponds to a single cell. Peptide identification is based on spectra analyzed by MaxQuant and is enhanced by using DART-ID to incorporate retention time information.

• Proteins-processed.csv
  • Proteins x single cells at 1% FDR, imputed and batch corrected.

• Cells.csv
  • Annotation x single cells. Each row corresponds to a single cell annotated with relevant metadata, such as, cell type if known, measurements from the isolation of the cell, and derivative quantities, i.e., rRI, CVs, reliability.
