NEBNext 接头是为 DNA、ChIP DNA 和 RNA(不包括 Small RNA)文库构建而设计的,能够确保接头的高效连接及文库的高产量,并且最大限度的减少接头二聚体的形成。NEBNext 接头包含一个特殊的发卡环状结构,能够更高效的和经末端修复的带 dA 尾的 DNA 结合。环状结构包含一个 U,当 U 被 USER 酶(由 UDG 和内切酶 VIII 组合而成)切掉后,环状结构打开,使它可以成为 PCR 的反应底物。检索序列通过 PCR 引入文库,从而实现了多样本的制备。NEBNext 接头引物不仅能够用于 NEBNext 产品,也可以用于其它的兼容 Illumina 标准平台的文库制备法。
提供单端和双端检索引物。同时也提供用于重亚硫酸盐测序的甲基化接头。
功能验证
每个试剂盒都通过对基因组 DNA、ChIP DNA 和 mRNA 进行文库构建,并在 Illumina 平台测序进行验证。
