		MSCC	Identification of the unmethylated region of a genome by pinpointing unmethylated CpGs at single base-pair resolution	[13,14]
Affinity enrichment	Moderate	MeDIP-seq	Generation of unbiased, cost-effective, and full-genome methylation levels without the limitations of restriction sites or CpG islands;	[1,76]
		MIRA-seq	Analyze recovered or double-stranded methylated DNA on a genome-wide scale; Applicable to various clinical and diagnostic situations.	[19]
		MDB-seq	Applied to any biological settings to identify differentially methylated regions at the genomic scale	[18]
		MethylCap-seq	Detection of differentially methylated regions with high genome coverage; Detect DMRs in clinical samples	[20,77]
Bisulfite conversion	High	BS-seq	Sensitively measure cytosine methylation on a genome-wide scale within specific sequence contexts	[48,78]
		RRBS	Analyze a limited number of gene promoters and regulatory sequence elements in a large number of samples; Analyzing and comparing genomic methylation patterns	[11,28]
		BSPP	Focus sequencing on the most informative genomic regions ;exon capturing and SNP genotyping; Detecting methylation in large genomes	[29]
		BC-seq	Detect site-specific switches in methylation; Determine DNA methylation frequencies in CGIs sampled from a variety of genomic settings including promoters, exons, introns, and intergenic loci	[30]
