DNA Methylation Microarray Service

CD genomics provides robust methylation profiling microarray service with extensive coverage of CpG islands, genes, and enhancers.

The Introduction to DNA Methylation Microarray

DNA methylation plays an important and dynamic role in regulating gene expression. DNA methylation is essential for normal development and is associated with a number of key processes including genomic imprinting, X-chromosome inactivation, suppression of repetitive elements, and carcinogenesis.

Utilizing the highly trusted, proven DNA analysis platforms in the industry, CD Genomics will assist you in the epigenome wide association studies, combining the comprehensive, expert-selected coverage and high-throughput compatible with large sample size.
