Age Prediction Based on DNA Methylation


Research on aging and longevity requires a higher level of professional technical support from life science service providers. CD BioSciences can help you achieve greater success in individual biological age prediction and aging and longevity research by providing DNA methylation age clock technology services.

DNA Methylation in Aging

What should we choose as a biomarker of aging? The researchers considered a range of indicators, such as brain, blood, DNA expression levels, and more, but the results were all unsatisfactory. Later experiments found that DNA methylation levels across the genome and at specific sequences were associated with age-related changes, with methylation levels at sites such as CpG islands tending to increase with age.

This discovery drives the development of age prediction models that allow us to build models based on the correlation between changes in DNA methylation levels and chronological age, using these models as a predictive benchmark to measure an individual's true biological age. At present, DNA methylation may be the most potential predictor of age, which can be used in individual health detection, disease prediction, and longevity research.

Our Services

We collect datasets including samples from different tissues/cells, analyze genomic DNA methylation status on a large scale with array/sequencing-based methods, calculate correlations between age and methylation levels by statistical analysis, and further develop age prediction models.

Age Prediction for Human
We provide customers human biological age clocks measurement services. Construct a variety of age prediction models and use various statistical methods to determine the actual age of individuals based on age-related methylation changes at specific CpG loci. You can provide blood, saliva, skin, or other tissue/cell samples according to actual specific needs.
