  1. For each spot we show the number given by PDQuest software, the accession number to the Swiss-Prot database, name, experimentally found (measured) and theoretical (theor.) relative molecular masses in kDa (Mr) and isoelectric points (pI), achieved sequence coverage (%), peptides sequenced by the LC-MS/MS, their composition, position and peptide score.
