Is there an optimal size for sonicated salmon sperm DNA for
transformation via Lithium/PEG ?
Current Protocols mentions that a range from 2-12 kb with a peak around
7kb for the smear (on a minigel) is good, but then in the same paragraph
it says bigger is better.
Is this just a trade of efficiency versus viscosity (handling?)
If a less-sonicated prep is diluted to 1mg/ml (from 10mg/ml) in fact better?
