Phusion high-fidelity DNA polymerases are composed of a DNA-binding domain fused to a Pyrococcus-like proofreading polymerase. Because of this, Phusion DNA polymerases produce PCR products with very high speed and accuracy. Also, Phusion DNA polymerases are tolerant of various inhibitors, allowing for robust amplification with minimal optimization. Phusion DNA Polymerase is an ideal choice for cloning and can be used for long or difficult (GC-rich) amplicons. Phusion high-fidelity DNA polymerases have become the choice for even demanding applications like massively parallel high-throughput sequencing of whole genomes. Other sizes are also available.
