1) The document discusses the workflow for quantitative proteomics data from QconCAT experiments, including the selection of QconCAT peptides, analysis and submission of the mass spectrometry data, and browsing/querying the results. 2) It describes the QconCAT Selection Wizard tool which takes protein sequences and filters peptides to find suitable QconCAT peptides based on uniqueness, detectability, and modifications. 3) The MCISB Proteome Database is presented as a searchable repository for quantitative proteomics data, including identifications and quantitations from QconCAT experiments. Future work includes integrating different quantitation methods and algorithms.
