Figure 3.
Thirty-six probes that displayed copy number differences from the previous experiment shown in Fig. 2 were analyzed by Southern blotting representations and genomic DNA from the two cell lines MDA-MB-415 (designated by M) and SKBR-3 (designated by S). Some of the blots are shown. Southern blot of representations (A,C,D) or genomic DNA (B) are shown for probes designated with CHP names. CHP0187 was a probe that detected no difference in copy number by array hybridization.
