Single-cell proteomics method: SCoPE2
Sample preparation method: nPOP
Model systems: Cell lines of monocytes (U937 cells) and Hela cells.
Application to the cell division cycle
Single-cell protein analysis using nPOP classified cells by cell type and by cell cycle phase. Furthermore, the data allowed us to quantify the covariation between cell cycle protein markers and thousands of proteins. Based on this covariation, we identify cell cycle associated proteins and functions that are shared across cell types and those that differ between cell types.

single cellsat 1% FDR. The first columns list the 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. See Specht et al., 2019 for details.
