Is there a quality difference between CompactPrep Plasmid Mega and Giga and the CompactPrep Plasmid Midi and Maxi Kits?
FAQ ID -1882

The quality of plasmid DNA prepared with CompactPrep Plasmid Midi and Maxi Kits is already very good – both Kits are suited for all routine applications including transfections of robust cell lines.

Due to a new wash-buffer included in the CompactPrep Plasmid Mega and Giga Kits, these kits yield plasmid DNA of even better quality, suitable for transfection of more sensitive cell lines as well.
