会不会是这个情况? Multimers are concatemers/fused products of several plasmids recombined together. Happens naturally if plasmids are cultivated in recA+ strains of bacteria. These plasmids are several times as large as the individual plasmid and therefore run very slowly in agarose (regardless of their conformation).
