DNA Methylation Age Prediction for Saliva

Most DNA methylation age clocks on the market today are models for blood samples, but saliva is also a common body fluid, and its DNA methylation pattern can also be used as a biomarker of aging. Saliva contains DNA methylation at some highly predicted CpG sites, which may provide the potential for highly accurate age prediction. As a service provider for aging research, CD BioSciences can provide professional support for DNA methylation analysis of various tissues and body fluids to customers worldwide.

Age Prediction Model for Saliva

With the continuous development of technology, several tissue-based models of DNA methylation have been generated in the field of epigenetics, and age-related CpG sites can be identified and applied, and some tissue-specific age prediction models have been constructed. Among them, the DNA methylation age prediction model based on saliva samples has specific CpG site markers, it is precisely because the saliva samples have a heterogeneous cellular composition, including oral epithelial cells and leukocytes, which enables the model to provide high predictive accuracy.

Our Services

CD BioSciences provides an age prediction service based on saliva samples, which analyzes the methylation status of the saliva genome through DNA methylation clocks and predicts the actual age of the samples. We develop and validate age prediction models, reducing customer analysis cost and time, providing cost-effective and potentially useful methods in the field of predicting age.
