Fig. 6From: High sensitivity isoelectric focusing to establish a signaling biomarker for the diagnosis of human colorectal cancerConvex hulls separating normal, CRC stage II and IV tissues. Convex hulls of the sets of all data points of each tissue class representing total pERK1 (ppERK1 + pERK1) peaks, SRC P6 and p70S6K P3 allowed separation of normal tissues (green) from CRC stage II (blue) and stage IV (red). Each dot represents a computationally analyzed data pointBack to article page
