Fig. 5From: Time dependent effect of cold ischemia on the phosphoproteome and protein kinase activity in fresh-frozen colorectal cancer tissue obtained from patientsUnsupervised hierarchical clustering of phosphopeptides. Unsupervised cluster analysis of the 2715 phosphopeptides detected in all t = 0 samples. Tumor samples are represented on the X-axis and the signal intensities of the phosphopeptides are represented on the Y-axis. Unsupervised clustering of three different tumors at four different time points shows a clear clustering of the samples per tumor indicating that cold ischemia does not obscure interpatient differences in the phosphoproteomeBack to article page
