", "Country": "XG", "Code": "Benefits", "Name": "Benefits" }, { "Language": "en", "Value": "The aptamer/polymerase mixture is a hot start system with reversible inhibition of the polymerase activity at lower temperatures. Polymerase inactivation is achieved by a tight bond of the folded aptamer-oligonucleotide to the active site of the polymerase at lower temperatures. Upon heating above +60°C, the aptamer acts like a molecular switch, changing its temperature-dependent tertiary structure and releasing the active polymerase. Dropping the temperature below +55°C shuts off the polymerase activity again. Similar to antibody-based methods, the enzyme is much more quickly activated by heating, than chemically modified polymerases. In contrast to antibodies, the aptamer-oligonucleotide is much more stable, allowing longer storage at room temperature.", "Country": "XG", "Code": "Background Information", "Name": "Background Information" }, { "Language": "en", "Value": "AptaTaq exo DNA Polymerase is active at temperature above +60 to +65°C and inactive below +55°C.
