The present invention relates to a method for the extension of an oligonucleotide primer with improved specificity using a specific oligonucleotide primer and a controller nucleotide, wherein the controller oligonucleotide enables sequence-specific strand opening of a double strand of extension product and template. The invention further relates to a respective kit for carrying out the method according to the invention.

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.

The present invention provides systems, devices, methods, kits, and compositions for nucleic acid analysis using digital PCR. In particular, methods are provided to analyze high titer samples that cannot be divided into a sufficient number of partitions containing zero nucleic acid molecules per partition to allow for Poisson analysis (digital PCR analysis).

System, including methods, apparatus, and compositions, for performing amplification assays with an amplification reporter including a first oligomer and a second oligomer capable of base-pairing with one another below a melting temperature of the reporter. The reporter may have a detectable photoluminescence that is affected, such as reduced, by base-pairing of the first and second oligomers with one another. A target, such as a nucleic acid target sequence, may be amplified in at least one volume, such as a plurality of partitions, above the melting temperature, and photoluminescence of the reporter may be detected from the at least one volume below the melting temperature. A property of the target, such as a concentration of the target, may be determined based on the photoluminescence detected.
