Enlarged sections of representative 2-DE gels. Enlarged sections of representative 2-DE gels showing differential expression of spots 7305, 5104 and 1606 between the metastic and non-metastic groups. The averaged relative intensities of particular spots in individual samples from the PDQuest output are shown in the bar graphs. The bars corresponding to the representative samples are marked. Sample order in the bar graph is the same as in Table 1 and in Table 2, the patient groups being separated.
