通常,使用基于 NEBNext EM-seq 酶学转化或重亚硫酸盐转化生成的 Illumina 文库,可以检测修饰的 5-甲基胞嘧啶(5mC)和 5-羟甲基胞嘧啶(5hmC)。但是,这些方法并不能区分 5mC 和 5hmC。
与 EM-seq 相同,NEBNext 酶学转化法 5hmC 甲基化建库试剂盒(E5hmC-seq)使用酶学转化法特异性检测 5hmC 位点,不会像重亚硫酸盐转化法对 DNA 造成损伤,即使 DNA 起始量低至 0.1 ng,也能灵敏地检测 5hmC 位点。
在两步酶法转化过程中,T4-BGT 对 5hmC 进行糖基化,使得 5hmC 在下一步 APOBEC 脱氨基反应中被保护了起来。T4-BGT 不保护 5mC 和未甲基化的胞嘧啶,它们被 APOBEC 脱氨基为尿嘧啶。随后使用 NEBNext Q5U®预混液(Q5® 高保真 DNA 聚合酶的改良版)进行扩增,并在 Illumina 平台上进行测序。
用于 EM-seq 和重亚硫酸盐测序的生物信息学分析工具也可用于 E5hmC-seq。可以从 EM-seq 数据中减去 E5hmC-seq 数据,从而确定单个 5mC 和 5hmC 位点的精确位置。
请注意试剂盒不包含引物,请单独购买(NEBNext 表观遗传建库多样本引物试剂盒,NEB #E3392、NEB #E3404)。
