In this iTRAQ quantification project, there were 6 Scophthalmus_maximus samples named CAA-1, CAA-2, CAA-3, Lys-Leu-1, Lys-Leu-2, Lys-Leu-3 and we did one technical duplicate experiments. Totally 935928 spectrums were generated, 32261 peptides and 5708 proteins were identified with 1% false discovery rate (FDR).
