title: Quantitation of rare DNAs by PCR.
abstract: This unit presents a protocol that uses the polymerase chain reaction (PCR) to quantitate the numbers of a particular DNA sequence, from 1 to 20,000 molecules per sample. In addition, it helps assess the presence of contaminating sequences, which can seriously affect the outcome of the procedure.
