Product description

Medino® Bst Plus DNA Polymerase is derived from Thermophilic Geobacillus sp DNA Polymerase I, lacking 5´-3´ exonuclease activity. The enzyme has stronger 5´-3´ DNA polymerase activity, strand displacement activity and dUTP tolerance, which is more suitable for anti-pollution isothermal amplification reactions, such as LAMP, CPA, etc.
