Age Prediction Based on DNA Methylation


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 increasing 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 the true biological age. DNA methylation may be the most potential predictor of age, which can be used in health detection, disease prediction, and longevity research.

CD BioSciences can help our clients achieve greater success in biological age prediction and aging and longevity research by providing DNA methylation age clock technology services.
