I think of some points.
1. Purity of the plasmid DNA. Is it almost completely pure covalently-closed circular
DNA? No contamination of host DNA of open-cicular DNA?
2. ExoIII digests DNA more processively at lower temp such as 30-C or 23-C. At 23-C,
if sufficient enzymes are supplied, ExoIII digest DNA in very synchronous manner
(apparently, of course).
3. ExoIII digest 3' end of " DOUBLE - STRAND " DNA. So, high temp or DMSO might
greatly inhibit ExoIII.
