The present invention provides a method for labeling unmethylated CpG dinucleotides within a DNA fragment, and use of the method in profiling of genomic DNA methylation. The present invention further provides modified DNA ethyltransferase enzymes and compounds which are capable of being used by the enzymes as cofactors for use in the labeling method.
本发明提供了一种标记 DNA 片段中未甲基化的 CpG 二核苷酸的方法,以及该方法在
基因组 DNA 甲基化分析中的应用。本发明进一步提供了修饰过的 DNA 乙基转移酶和能被酶用作辅助因子的化合物,以用于标记方法。
