WebHDA system using bacterial UvrD DNA helicase The first HDA system developed used the E. coli UvrD helicase, in which several hundred base pairs of DNA were amplified in the presence of DNA polymerase and two accessory proteins in vitro [22]. E. coli UvrD helicase (*82 kDa) was chosen due to its ability to unwind blunt-end dsDNA. WebSince its description in 2004, isothermal helicase-dependent amplification (HDA) has been successfully applied in the development of novel molecular-based technologies for …

This thermostable helicase is capable of unwinding blunt-end nucleic acid substrates at elevated temperatures (60° to 65°C). The HDA reaction can also be coupled with reverse transcription for ...
WebAug 15, 2008 · Helicase-dependent amplification (HDA) is a novel isothermal DNA amplification method (Vincent et al., 2004). Like PCR, it amplifies a target sequence using two flanking primers, but it uses helicase to separate template DNA duplex instead of heat, eliminating the need for thermal cycling. In HDA reactions, the helicase unwinds the …
