Long-PCR Reagents and Guidelines General guidelines for long-PCR conditions and enzyme mixtures. Efficient long-PCR results from the use of two polymerases: a non-proofreading polymerase is the main polymerase in the reaction, and a proofreading polymerase (3' to 5' exo) is present at a lower concentration. Includes: For PCR with low-complexity templates (e.g., plasmid and cosmid inserts); For PCR with moderate-complexity templates (e.g., bacterial genomic DNA); For PCR with high-complexity templates (e.g., human genomic DNA).
Quantitation of Rare DNAs by PCR Protocol 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.
Quantitative PCR Protocol II Quantitative PCR involves co-amplification of two templates: a constant amount of a preparation containing the desired target sequence and serial dilutions of a reference template that is added in known amounts to a series of amplification reactions. The concentration of the target sequence is determined by simple interpolation into a standard curve.
