Superior target yields with Phire Hot Start II PCR Master Mix. Equal volumes of the reaction were analyzed on a 2% agarose gel. Hot start PCR is a modified form of conventional polymerase chain reaction (PCR) that reduces the presence of undesired products and primer dimers due to non-specific DNA amplification at room (or colder) temperatures. Notice to Purchaser This enzyme is specifically optimized for increasing base incorporation rate by inactivating 5’->3’ exonuclease activity. required for a PCR protocol, it is advisable to design primers suitable for a two-step PCR protocol, if possible. In contrast, the PCR protocols for hot-start Taq DNA polymerases were substantially longer and resulted in lower product yields. Off-target amplification can become a serious problem when PCRs are performed with low concentrations of a complex template, such as mammalian genomic DNA template (Chou et al.
