This completely revolutionizes the way one approaches PCR-based quantitation of DNA and RNA. In real-time PCR (qPCR), reactions are characterized by the point in time during cycling when amplification of a target is first detected rather than the amount of t...
Two sets of PCR primers (methylation and non-methylation) are designed to differentiate the methylation state of a locus based on amplification of the bisulfite-treated DNA. Unmethylated DNA is present as single strands after bisulfite treatment ...
Thermostable DNA polymerases used for basic PCR require a DNA template, and as such, the technique is limited to the analysis of DNA samples. Yet numerous instances exist in which amplification of RNA would be preferred. To apply PCR to the study of RNA, the RNA sample must first be conver...

The method of homologous recombination PCR (polymerase chain reaction) is a powerful technique used in molecular biology to introduce specific mutations or modifications into a DNA sequence. This technique combines the principles of PCR amplification and homologous recombination to facilitate the precise ma...
