Fast PCR enzymes shorten cycling times, thus reducing time from sample to results and increasing throughput. Phusion and Phire DNA Polymerases incorporate more nucleotides per binding event as compared to other polymerases. This high procesivity allows the use of very short extension times and results in very short overall PCR cycling.
