  • Publication number: 20230287384
    Abstract: There is described herein, a method of capturing cell-free methylated DNA from a sample having less than 100 mg of cell-free DNA, comprising the steps of: subjecting the sample to library preparation to permit subsequent sequencing of the cell-free methylated DNA; adding a first amount of filler DNA to the sample, wherein at least a portion of the filler DNA is methylated; denaturing the sample; and capturing cell-free methylated DNA using a binder selective for methylated polynucleotides.
    Type: Application

  • Publication number: 20220251665
    Abstract: There is described herein a method of detecting the presence of DNA from cancer cells in a subject comprising: providing a sample of cell-free DNA from a subject; subjecting the sample to library preparation to permit subsequent sequencing of the cell-free methylated DNA; adding a first amount of filler DNA to the sample, wherein at least a portion of the filler DNA is methylated, then optionally denaturing the sample; capturing cell-free methylated DNA using a binder selective for methylated polynucleotides; sequencing the captured cell-free methylated DNA; comparing the sequences of the captured cell-free methylated DNA to control cell-free methylated DNAs sequences from healthy and cancerous individuals and from individuals with distinct cancer types and subtypes; identifying the presence of DNA from cancer cells if there is a statistically significant similarity between one or more sequences of the captured cell-free methylated DNA and cell-free methylated DNAs sequences from cancerous individuals.
