Method for the specific detection of nucleic acids in a sample by reaction of the sample with one or several labelled nucleotide triphosphates and one or several enzymes which catalyse the production of a labelled nucleic acid B which contains this nucleotide, non-thermally denaturation, reacting the sample with a nucleic acid probe C which is sufficiently complementary to nucleic acid B and which contains at least one immobilizable group, if desired, contacting the nucleic acid hybrid D formed with a solid phase which recognizes and binds the immobilizable group, removing the liquid from the solid phase and determining the label on the solid phase as a measure for the presence of the nucleic acid.

Method for the sensitive detection of nucleic acids

Process for the production of nucleic acids by hybridization of at least one primer to a template nucleic acid and enzymatic elongation of the primer to a nucleic acid strand which is complementary to the template nucleic acid by reaction with different types of nucleoside triphosphates, wherein the complementary nucleic acid strand carries two or more groups which enable it to be immobilized and one or more detectable groups, a method which uses this process for the detection of nucleic acids, suitable reagent kits therefor and modified nucleic acids.

Process for the production of modified nucleic acids

Method of detecting nucleic acids whose nucleotide sequences differ from one another at a position X. The method uses a set of oligonucleotides where the nucleotides found at position X are complementary to a variant nucleic acids only at this position X. However, with respect to the position of another mismatch Y, the nucleotide sequences thereof differ from one another. The invention further addresses reagents for performing the methods as well as reagents and applications of the method.

Method of detecting variant nucleic acids using extension

Simultaneous sequencing of nucleic acids

For the detection of nucleic acids of definite sequence by hybridisation with a complementary nucleic acid probe which contains bound via a chemical bonding at least one hapten as labelling one uses, as hapten, a steroid which is bound vie a bridge of at least 4 atoms length to at least one position of the nucleic acid probe which does not participate in hydrogen bridge formation and detects the hybridised probe via an in turn labelled anti-hapten antibody.

Process for the detection of nucleic acids

Method of determining polymerase activity by incubating the polymerase with a template nucleic acid, one detectable mononucleoside triphosphate and one immobilizable nucleoside triphosphate, binding the immobilizable nucleotides to a solid phase and detecting the bound delectable nucleotides and tests based thereon.

Reagents and kits for determining polymerase activity

Method of detecting variant nucleic acids

Process for the specific production of nucleic acids based on the principle of transcription in which a promoter oligonucleotide and a template-specific oligonucleotide which can hybridize with it are used as a promoter reagent and a process for nucleic acid detection which is based on this process.

Promotor controlled specific amplification of nucleic acid sequences

Method of determining polymerase activity

Process for the production of ribonucleic acids or for the detection of template nucleic acids based on a transcription technique using two oligonucleotides which can hybridize to adjacent regions on the template nucleic acid without ligation of these oligonucleotides.

Process for the specific production of ribonucleic acids

The present invention provides a process for the detection of nucleic acids of definite sequence by hybridisation with two single-stranded nucleic acid probes present in the same solution phase complementary to different regions of the nucleic acid to be detected, one nucleic acid probe serving as detector probe and containing as labelling at least one hapten bound via a chemical linkage and the other nucleic acid probe serving as capturing probe and being bound to a solid matrix, wherein, as hapten, a steroid is used which on at least one position of the detector probe, which does not participate in the hydrogen bridge formation with the nucleic acid to be detected, is covalently bound via a bridge of at least four atoms, the nucleic acid to be detected, present in solution, is incubated with the detector probe and the capturing probe in any desired sequence, whereby the binding of the capturing probe on the matrix with the nucleic acid to be detected is brought about before, during or after the incubation, the remaining solution is separated off from the matrix-bound complex of the capturing probe, nucleic acid to be detected and detector probe and the complex detected via an anti-hapten antibody which is labelled.
