The present invention refers to a formal-in-free fixative composition, suitable for the fixation of cells in particular in liquid samples, the use of said fixative for the treatment of biological samples, a method for the treatment of cell-comprising liquid samples, a kit comprising said fixative and a method for diagnosis... Qiagen Gmbh

Optimization of dna amplification reactions

The present invention relates to methods and uses where a combination of (i) an enzyme exhibiting 5′->3′ exonuclease activity and specifically degrading 5′-phosphorylated strands of double-stranded nucleic acids is used, and (ii) one or more primer pair(s), each primer being 5′ phosphorylated, in a method comprising at least a first... Qiagen Gmbh

Method of amplification of a short tandem repeat locus

Short tandem repeat (STR) markers are genetic elements that are frequently used in the fields of forensic analysis, paternity determination and detection of genetic diseases and cancers. Such analysis involves the amplification of STR loci. Technically, this can be challenging due to sequence variations in the flanking regions of the... Qiagen Gmbh

Internal amplification control

The invention addresses these issues by means of an internal amplification control consisting of a set of primers and an artificial template. The primers define two fragments of different sizes. The examples show that this system allows the researcher to distinguish between the presence of inhibitors and sample degradation.... Qiagen Gmbh

Nucleic acid amplification method

The invention relates to a method for the simultaneous detection of at least four nucleic acids labeled with a covalently attached dye in a sample comprising the step of detecting the fluorescence emission of said fluorescent dyes upon excitation, wherein the at least four dyes attached to said nucleic acids...
