1月10日,Life Technologies(Ion Torrent)发布Ion Proton™ Sequencer。就在同一天,Illumina也发布Hiseq 2500。测序技术的竞争已经进入白热化,都在瞄准1000美元测个体基因组的目标。Ion Torrent说年末就能达到,而Illumina反击说他们在夏天就能实现。让我们拭目以待吧。
(目前的形势是Illumina一直领先,从reads长度、测序通量、价钱等方面都要优于Ion Torrent。但Ion Torrent采用的是不同的测序技术(Semiconductor Sequencing),所有测序进程都在一个芯片上完成。如果要升级机器,只需要更换新的芯片即可。Ion Torrent很有可能后来居上。)
(最近比较忙,先发布出来,以后再慢慢分析,有兴趣的直接看英文报道。)
