Polypeptide pattern distinguishing HSCT patients with aGvHD from HSCT controls. This figure shows the compiled data sets of 13 GvHD samples (A, top left panel) and 50 HSCT control (top right panel) of the training set (Table 1). Normalized molecular weight is plotted against normalized migration time. The mean signal intensity is color coded. (B) The bottom panel depicts the 31 indicative polypeptides defining the specific pattern for GvHD (bottom left panel) and controls (bottom right panel).
