Methylation Controls

Scientific Overview

Keep your DNA methylation experiments in control. EpigenDx offers methylated genomic DNA controls to serve as positive or negative controls in DNA methylation analysis experiments. The controls have been used on more than 14,000 gene-specific and global methylation assays using targeted bisulfite NGS (tNGBS), Pyrosequencing, and MS-HRM. They are recommended for use in DNA methylation assay development, optimization, and validation to ensure assay linearity, specificity, and reproducibility for research and clinical applications.

Available in human, mouse, rat, monkey, as well as custom species.

Methylation Control Applications

Methylation control DNAs are useful for ensuring quality assay results in epigenetic studies.  They can be used in various DNA methylation analysis methods to ensure the assay in use provides quality data from unknown samples.  Bisulfite conversion techniques, bisulfite sequencing, MS-HRM, Infinium Methylation EPIC Array, methyl-DNA immunoprecipitation (Me-DIP), methyl-CpG binding domain-based (MBDCap) proteins, methylation-specific PCR (MSP), and real-time PCR are all methods in which these methylation controls could be utilized.

Quantitative Methodology Is Critical

Quantitative methodology is critical for assessing DNA methylation. The identification of appropriate promoter regions or key CpG dinucleotides that influence transcription for individual genes is also important The human genome contains ∼30,000 CpG islands (CGIs), long stretches (0.5–2 kb) of DNA with unusually elevated levels of CpG dinucleotides. In mammalian genomes, DNA methylation occurs at CpG dinucleotides and is a dynamic epigenetic control mechanism. At these locations, methylated CpG dinucleotides can cause a high rate of C to T substitution. It is well known that methylated CpG sites have a high mutation rate.

MS-HRM (Methylation-Sensitive High Resolution Melting) is a PCR-based in-tube approach for detecting methylation levels at specific loci. The assays have a high sensitivity, allowing detection of 0.1-1% methylation alleles in an unmethylated background, thanks to a novel primer design. MS-HRM primers are designed to complement the methylated allele, and a specific annealing temperature allows these primers to anneal to both the methylated and unmethylated alleles, increasing the assay’s sensitivity.
