Illumina 接头系列

测序的第一步是通过DNA或RNA构建文库。如图1所示,文库中包含DNA插入片段(DNA Insert),两端各有一个接头。

图1:双index文库片段示意图

接头包含:

  • P5和P7序列:允许文库结合且能在flow cell上生成簇的序列

  • Rd1 SP和Rd2 SP:启动测序的测序引物结合位点

  • Index 1和Index 2:用于样本区分的index序列,可允许单次测序或单个Flow Cell通道中混合多个样本

Illumina提供多种接头试剂盒来实现更灵活和多样性的index策略,Illumina接头试剂盒之间的差异主要基于支持的样本数量,index的长度和序列,和连接到插入片段的化学方法的不同。

以下表格列出了Illumina接头试剂盒的产品规格:

  • 复杂性指每个试剂盒中index序列种类的数量

  • Index长度指分别读取index 1和index 2所需的测序循环数量
