Global DNA 5mC Measurements


DNA methylation refers to the process of adding a methyl group to the C5 position of a cytosine base in DNA under the action of DNA methyltransferase, thereby producing 5-methylcytosine (5mC). And studies have found that during the aging process and the development of related diseases, the overall DNA methylation level in the genome changes. Therefore, accurate measurement of total 5mC levels can help researchers better understand the role of DNA methylation in aging and related diseases.

With an advanced technology platform and extensive expertise, CD BioSciences provides customers with global DNA 5mC measurement services to better understand the role of DNA methylation in aging.


DNA methylation plays an important role in the aging process and is also implicated in many age-related diseases. Abnormal methylation levels may lead to many diseases, so 5mC as an indicator of methylation level also has potential as a biomarker for certain diseases. Therefore, researchers began to use different analytical methods to analyze DNA 5mC content. For quantification of 5mC, the molar amount of the compound is determined primarily using an absolute calibration model to isotopically labeled cytosine 13C15N2, or ratios based on the sum of the molecules of cytosine.

Our Services

We provide an easy-to-use high-throughput assay to quantify global levels of DNA methylation 5mC. Changes in global DNA methylation have been observed in cells/tissues of different growth and development states provided by customers, including research analysis of age-related diseases such as cancer.

We offer methods commonly used to measure global DNA methylation levels, including LC-MS/MS methods, ELISA assays, spectroscopy, and more. These rich methods make measurement optional, easier and more cost-effective for customers. Our specific measurement service process is as follows.
