Nuove metodiche di sequenza del DNA

“A new method of DNA sequencing published this week in science identifies incorporation of single bases by fluorescence. This has been shown to increase read lengths from 20 bases (454 sequencing) to >4000 bases, with a 99.3% accuracy. Single molecule reading can reduce costs and increase the rate at which reads can be performed. ‘So far, the team has built a chip housing 3000 ZMWs [waveguides], which the company hopes will hit the market in 2010. By 2013, it aims to squeeze a million ZMWs [waveguides] onto a single chip and observe DNA being assembled in each simultaneously. Company founder Stephen Turner estimates that such a chip would be able to sequence an entire human genome in under half an hour to 99.999 per cent accuracy for under $1000.'”
