Expedeon MagniPhi & QualiPhi DNA Polymerases

Expedeon has launched two high-fidelity polymerases, MagniPhi DNA Polymerase and QualiPhi DNA Polymerase. Expedeon offers the products in both 25- and 100-reaction kits, which contain DNA polymerases and their associated reaction buffers. The firm said MagniPhi — a wild-type form of the Phi29 DNA polymerase — is ideal for isothermal DNA amplification. According to Expedeon, MagniPhi's fidelity of synthesis produces up to 100 times fewer errors than Taq polymerase, while the amplification reaction yields more whole-genome amplification compared to normal PCR-based WGA techniques.

Expedeon's QualiPhi — a chimeric form of the Phi29 DNA Polymerase — has been engineered for enhanced sensitivity and efficiency while preserving the high processivity of the wild type Phi29. According to the firm, the polymerase's higher sensitivity allows improved amplification of DNA from low to high input concentrations and higher yields than the wild-type polymerase.
