Cat. NO. AB-RK21003 (datasheet)

phi29 DNA Polymerase is a replicative polymerase from the Bacillus subtilis phage phi29. phi29-fast DNA Polymerase has been genetically engineered to enhance the amplification efficiency by fusing DNA binding domains to the polymerase.
phi29-fast DNA Polymerase has exceptional strand displacement and processive synthesis properties. The polymerase has an inherent 3'→5' proofreading exonuclease activity. Compared with the traditional phi29 DNA polymerase, phi29-fast DNA polymerase has displayed an improved and faithful multiply primed DNA amplification proficiency on both circular plasmids and genomic DNA.
phi29-fast DNA Polymerase has advantaged in replication requiring a high degree of strand displacement and/or processive synthesis, as well as high fidelity and efficient replication at moderate temperatures.
