(Left) FIGE analysis of a NotI-digested 140-kb BAC clone (lane sB) and 18 of its deletions arrayed according to decreasing size of insert DNA. A 5-kb ladder and 8–48 kb molecular weight standards were applied to lanes m2 and m1, respectively. (Right) A similar analysis with a 140-kb PAC clone (lane sP) and 25 of its deletions. A 5-kb ladder is included in lane m2. The numbers on either side indicate the size in kb pairs of bands from the 5-kb ladder molecular weight standard.
