pBR322-derived multicopy plasmids harboring large inserts are often dimers in Escherichia coli K-12.
pBR322-related plasmids that are 2.3 to 5.1 kb were found predominantly as monomers, while plasmids that are 7.7 to 15.2 kb were found predominantly as dimers in rec+ cells of Escherichia coli K-12.
