Method for identifying the quantitative cellular composition in a biological sample

Abstract

The present invention provides an epigenetic haemogram, also referred to as an epigenetic blood cell count that identifies the quantitative, comprehensive picture of cellular composition in a biological sample, wherein advantageously a normalization standard is used. The normalization standard is a nucleic acid molecule comprising at least one marker-region being specific for each of the blood cells to be detected, and at least one control-region being cell-unspecific, wherein said regions are present in the same number of copies on said molecule and/or a natural blood cell sample of known composition. Furthermore, the present invention relates to a kit and the use of a kit for performing the epigenetic assessment of comprehensive, quantitative cellular composition of a biological sample. The biological sample is derived from e.g. a mammalian body fluid, including peripheral, capillary or venous blood samples or subfractions thereof, such as peripheral blood mononuclear cells or peripheral blood monocytes, or a tissue sample, organ sample, or from frozen, dried, embedded, stored or fresh body fluids or tissue samples.
