Towards reproducibility in large-scale analysis of protein–protein interactions

Co-fractionation mass spectrometry (CF-MS) has the potential to measure thousands of protein complexes in a single experiment, but the field is still in its infancy. A meta-analysis of CF-MS data yields a core CF-MS interactome and a tool allowing researchers to align new results to published data.
