Tte UvrD Helicase is a repair helicase capable of unwinding double-stranded DNA, without a requirement for a specific flap or overhang structure, from the thermophilic organism Thermoanaerobacter tengcongensis. It is active on a wide range of DNA substrates and, along with its thermostability (active to 70°C), Tte UvrD Helicase has been demonstrated to be a useful additive for improving specificity of isothermal amplification reactions, particularly in conjunction with the WarmStart® LAMP Kit (DNA & RNA).

Tte UvrD Helicase Eliminates Non-Template Amplification in LAMP Reactions

Tte UvrD Helicase | NEB酶试剂 New England Biolabs

LAMP reactions were performed using the WarmStart® LAMP Kit (DNA & RNA) (NEB #E1700) and a primer set prone to high levels of non-template amplification. Without Tte UvrD Helicase (left), the positive reaction (+DNA) amplifies in ~8 minutes while the no-template control (NTC) amplifies in ~20 minutes. In the presence of 10 ng Tte UvrD Helicase (right), the positive reaction maintains its rapid amplification time with a slight reduction in total RFU, while the NTC reaction is completely suppressed.


Tte UvrD Helicase is isolated from a strain of E. coli which carries the cloned UvrD gene from Thermoanaerobacter tengcongensis.
