Hot-start PCR prevents the amplification of non-specific products, amplifies low abundance targets and offers convenient room temperature reaction setup. We offer different hot-start DNA polymerases to support your everyday research needs. This includes Thermo Scientific DreamTaq Hot Start DNA Polymerase, which is an enhanced hot start Taq DNA polymerase suitable for most PCR applications. DreamTaq Hot Start offers higher sensitivity, specificity, and yields compared to conventional hot start Taq DNA polymerase.
