In case of nested PCR, the target sequence is amplified using a pair of PCR primers, and a portion of the amplification product is reamplified using another pair of PCR primers complementary to the regions located immediately beyond the 3'-ends of the first pair of primers.

In case of nested PCR, the inner primers have a lower annealing temperature than that of the outer pair. For the initial several cycles of PCR the higher denaturation and annealing temperatures are used; as a result, only the outer pair of primer is able to prime amplification.
