Hot start PCRis a novel form of conventional polymerase chain reaction (PCR) that reduces the occurrence of undesired products and formation of primer-dimers due to non-specific DNA amplification at room temperatures. This enables hot-start PCR, where polymerase activity is eliminated or minimized at temperatures below 70°C. The purpose of hot start polymerase chain reaction (PCR) is to optimize the yield of the desired amplified product in PCRs and, simultaneously, to suppress nonspecific amplification and formation of primer dimers. Thus, if a synthetic oligonucleotide is annealed to a single-stranded template that contains a region complementary to the oligonucleotide, DNA polymerase … the speed and ease of use, sensitivity, specificity and robustness of PCR has revolutionized molecular biology and made PCR the most useful and powerful technique with great spectrum of research and diagnostic applications.

TriLink has applied their expertise in modified nucleic acid chemistry to develop chemically modified dNTPs and primers that enable Hot Start PCR using standard Taq DNA polymerase. Hot start PCR is a variant of the polymerase chain reaction (PCR) developed to suppress enzymatic activity (usually Taq DNA polymerase) until the first denaturation step has been accomplished.This avoids having the PCR reaction sit at room temperature during assay setup (and prior to thermal cycling) when nonspecific amplification, a cause of PCR failure, can occur. Hot Start PCR (Protocol summary only for purposes of this preview site) Mispairing of primers, which occurs at suboptimal annealing temperatures, leads to the synthesis of nonspecific PCR products.
