Efficiency of methylated DNA immunoprecipitation bisulphite sequencing for whole-genome DNA methylation analysis


Jeong HM et al.

We compared four common methods for measuring DNA methylation levels and recommended the most efficient method in terms of cost and coverage.

MATERIALS & METHODS:

The DNA methylation status of liver and stomach tissues was profiled using four different methods, whole-genome bisulphite sequencing (WG-BS), targeted bisulphite sequencing (Targeted-BS), methylated DNA immunoprecipitation sequencing (MeDIP-seq) and methylated DNA immunoprecipitation bisulphite sequencing (MeDIP-BS). We calculated DNA methylation levels using each method and compared the results.

RESULTS:

MeDIP-BS yielded the most similar DNA methylation profile to WG-BS, with 20 times less data, suggesting remarkable cost savings and coverage efficiency compared with the other methods.

CONCLUSION:

MeDIP-BS is a practical cost-effective method for analyzing whole-genome DNA methylation that is highly accurate at base-pair resolution.
