Especially for the cloning with 'blunt-ended' DNA, the concentration of 'blunt'-DNA-ends plays a crucial role for the successful cloning.
Substances, that increase the so-called 'macromolecular crowding' and condense DNA molecules into aggregates, concentrate the
DNA and increase the possibility, that DNA ends will meet and thereby improve the cloning result.
So, the DNA and enzyme concentration can be reduced.
Besides, such substances reduce the intramolecular ligation (religation).
For 'blunt end' cloning the recommended Polyethylene glycol 8000 concentration is 15%.
