System Suitability Study, were analyzed along with the TCGA Ovarian Cancer tumor samples. Pacific Northwest National Laboratory conducted iTRAQ experiments that included proteome (5 Data sets) and phosphoproteome (4 Data sets) interrogation of both the P5 (basal) and P6 (luminal) human-in-mouse xenograft breast carcinoma pooled samples. Johns Hopkins University performed 6 iTRAQ proteome experiments. The CompRef experiments were intercalated between the TCGA Ovarian Cancer experiments to monitor the consistency of laboratory protocols and mass spectrometry instrument performance.]]>
