Fig. 4.

Representative examples of BEAMing assays from the indicated patients and lesions. In patient 13, the mutation shown represents one that was present in a new metastasis that occurred 29 months after chemotherapy (see Application to Individual Patients). The red dots correspond to beads attached to mutant DNA fragments [labeled with phycoerythrin (PE)], the blue dots correspond to beads attached to WT DNA fragments [labeled with fluorescein (FITC)], and the black dots correspond to beads attached to both WT and mutant DNA fragments.
