Abstract: A method of detecting death of a cell type or tissue in a subject is disclosed. The method comprises determining whether cell-free DNA comprised in a fluid sample of the subject is derived from the cell type or tissue, wherein the determining is effected by ascertaining the methylation status of at least four methylation sites on a continuous sequence of the cell-free DNA, the sequence comprising no more than 300 nucleotides, wherein a methylation status of each of the at least four methylation sites on the continuous sequence of the DNA characteristic of the cell type or tissue is indicative of death of the cell type or tissue. Kits for detecting cell death are also disclosed.

Abstract: The present disclosure relates generally to compositions and methods for determining cell type based on a methylation profile of associated DNA. For cell free DNA, such determination can be used to identify disease or conditions relating to the cell type. For tumor cells, such determination is useful for identifying their primary origin.

Abstract: A digital droplet PCR method of analyzing the methylation status of methylation sites of a double-stranded DNA molecule which comprises at least two methylation sites per single strand of the double-stranded DNA molecule is disclosed.
