Nested PCR could be performed by using an aliquot of a first PCR run (
usually 1 ul) employing one or two "new" primers which are capable of
binding within the first amplificate, therefore designated as "nested-primer"
PCR. The advantage and disadvantage is the enormous sensitivity which can
easily cause contaminations. This approach is able to amplifiy single copies
which such an efficiency that the resulting PCR products can be directly
