PCR Techniques · Pathology

Which PCR technique is specifically designed to amplify a target with extremely low copy numbers by using two sets of primers in successive reactions?

  1. Multiplex PCR
  2. Nested PCR method
  3. Allele-specific PCR
  4. Reverse Transcriptase PCR
Show answer and explanation

Correct answer: Nested PCR method

Nested PCR uses an outer set of primers for an initial round of amplification, followed by a second round using an inner (nested) set of primers. This significantly increases both the sensitivity and specificity of the detection.
