WebJul 9, 2004 · In living organisms, a DNA helicase is used to separate two complementary DNA strands during DNA replication (Kornberg & Baker, 1992). We have devised a new isothermal DNA amplification technology, helicase-dependent amplification (HDA), by mimicking nature. HDA uses a DNA helicase to separate double-stranded DNA (dsDNA) … 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.
