All the answers I am reading are concerned by a new amplification after
purification of the amplified fragment(s).
But did somebody a re-amplification directly in the "first" mixture or from
an aliquot, e.g. because the amplification is very slight, or for practical
purposes (as routine diagnosis) ?
In this case is the "nested" PCR the only way to re-amplify ?
Thanks in advance
