Decatenation of k-DNA by A59₂B₂ and A₂B₂. Reactions contained k-DNA at 13.3 μg/ml and were incubated for 1 hr at 37°C. Samples were analyzed on a 1% agarose gel (1 m.c., free monomeric minicircle; 2 m.c., two interlinked minicircles; 3 m.c., three interlinked minicircles; s/c m.c., supercoiled minicircle). The unresolved k-DNA network remains in the wells.
