The year before, Nyren’s lab had also spun off a company, Pyrosequencing AB, to refine and commercialize the technology. Pyrosequencing was not the firm that would bring the technology to market, however; that distinction went to Connecticut-based 454 Life Sciences, who licensed whole-genome pyrosequencing applications in 2003. 454 made chips which enabled highly efficient, parallelized sequencing reactions and released the GS20 sequencer in 2005 for the price of $500,000. The GS20 worked by attaching each individual DNA template molecule to a bead and copying it many times using polymerase chain reaction (PCR). Each bead was then loaded into a well in a microplate, where sequencing reactions would be carried out. The light from luciferase activation could be detected through the bottom of the wells, enabling sequences to be read.

郭晓东:我经常骑着自行车,到处找工作。我做过很多工作,在歌厅唱歌、当主持,“下面有请几号台的李先生唱歌”,就是这种主持。还做过一个,我到现在都叫不出名字,去各个小区统计有多少栋楼和多少户人家,然后去发擦手油的传单。我干了很久这样的工作,后来我就在想,我适合干这个吗?我不知道。
