摘要: Background The field of proteomics involves the characterization peptides and proteins expressed in a cell under specific conditions. Proteomics has made rapid advances recent years following sequencing genomes an increasing number organisms. A prominent technology for high throughput analysis is use liquid chromatography coupled to Fourier transform ion cyclotron resonance mass spectrometry (LC-FTICR-MS). Meaningful biological conclusions can best be when peptide identities returned by this technique are accompanied measures accuracy confidence.
