  1. Protein spots were analyzed via LC-ESI-MS-Q/TOF and identified using the MASCOT search engine. MW (Da) – theoretical molecular weight in Dalton; pI ~ – theoretical pI; MS/MS score – protein score given by Mascot; % Seq – percentage sequence coverage; Pep match – number of peptides assigned to protein; K test – D value from Kolmogorov-Smirnov test (0.10, D > 0.642); Fold FBS 0%/10 % – fold optical density of the protein spot (expression) for serum depleted proteomes (0 % FBS) compared to control proteomes (10 % FBS); a – uniquely expressed protein spot. Relevant GO terms for molecular function and biological process are used
