SMRT 全称为 Single Molecule Real-Time,也就是单细胞实时测序技术,它运用的依旧是边合成边测序的思想。 SMRT 测序使用的Cell 是一张厚度为100 nm的金属片,一面带有几十上百万个直径为几十纳米的小孔,称为零模波导孔(zero-mode waveguide,ZMW)。 在纳米孔底部,锚定着测序模板(DNA单链)和DNA聚合酶,同时包含着...
HiFi sequencing is a single-molecule, real-time sequencing technology (SMRT) that provides incredible single-molecule read accuracy across long reads of tens of kilobases in length or more. HiFi reads are generated by combining information from multiple observations of a single DNA molecule, resulting...
随着基因组研究的不断推进,以PacBio测序为代表的第三代基因测序技术逐渐应用到多个科研领域。该平台利于单分子实时测序技术,又称作SMRT(Single Molecule Real-Time)测序,基于纳米小孔的单分子读取技术,无需扩增即可快速完成序列读取。 1.仪器 Pacific Biosciences于2004年成立,最初是基于康奈尔大学的一项研究而起步。2010...
