A method for the quantitative determination of the number of at least one predetermined sequence in a biological sample comprises the steps: a) providing a biological sample containing a nucleic acid, b) fragmenting the nucleic acid contained in the biological sample, c) dividing the sample obtained in the step b) into y subsamples, d) adding at least two primer pairs to each of the at least two subsamples, where to each of the subsamples the same primer pairs are added, and where the individual primer pairs are adapted to amplify, in an amplification reaction, subsequences of the predetermined sequence that are different for each primer pair, e) carrying out an amplification reaction with each of the at least two subsamples obtained in the step d), f) determining the number of different amplification products obtained with the amplification reactions in the step e) for the individual sub samples and the determination of the number of subsamples in which identical amplifications products have been obtained.

The invention relates to a method for the quantitative analysis of the number of a pre-determined sequence, and optionally of sequences homologous to the pre-determined sequence, in a biological sample, whereby a defined quantity of a biological sample is subjected to at least one amplification reaction which is adapted in such a way as to amplify at least two non-homologous sequences contained in the pre-determined sequence. The number of different amplification products obtained is then determined and compared with a frequency distribution. The invention further relates to a kit for the quantitative analysis of the number of a pre-determined sequence in a biological sample, and a device which is especially suitable for carrying out the inventive method.

A method for concentrating materials in a liquid involves pouring the liquid into a material-containing receptacle and irradiating the liquid by acoustic waves so that a stationary flow pattern with different flow rate areas is formed in the receptacle. A concentration device and reaction method using such concentration are also provided.

The invention relates to a method for the amplification of genetic information, wherein it is possible to analyze the frequency of unlimited partial amounts of genetic material from very small sample amounts. The inventive methods enable parallel amplification of specific target sequences of the respective partial amounts and simultaneous qualitative analysis thereof and subsequent relative quantitative analysis, wherein several high concentration amplification products containing many target sequences and qualitatively high value amplification products are provided.
摘要:
The invention relates to a method for carrying out an enzymatic reaction, in particular for carrying out a polymerase chain reaction (PCR). Said method consists of the following steps: at least one eukaryotic cell is removed from a starting material; the cell core or cores of the eukaryotic cell(s) is/are coloured; at least one eukaryotic cell is deposited on a reaction point of a solid substrate in a liquid volume of less than 10 μl; it is detected whether at least one coloured cell core is present on a reaction point of the substrate, subsequently, an enzyme and optionally a reaction buffer is added to the eukaryotic cell(s) and the enzymatic reaction is subsequently started. Preferably, the claimed invention is carried out using a flow cytometer.
摘要:
A method is provided for characterizing a mixed sample having at least two particles with nucleic acids from different individuals, where each particle has nucleic acid from one or more individuals, in particular for the quantitative determination of the absolute and/or relative copy number of a predetermined sequence of an individual, of which nucleic acid is present in the mixed sample, having the steps: a) isolating the particles and applying at least two individual particles to a substrate, where each of the at least two particles is deposited in each case individually to a hydrophilic reaction site, surrounded by a hydrophobic zone, of the substrate in a volume of less than 10 μl so that precisely one particle is present per reaction site, b) analysis of at least two of the particles deposited to the substrate at the reaction site of the substrate to assign each of the particles to individuals from the mixed sample by genotyping, where at least 80% of the particles analysed are to be assigned to an individual, and c) further characterization of the analysed particles. Moreover, a kit which is suitable in particular for carrying out this method, is also provided.
