Definitions

  • the invention relates to a method according to the preamble of claim 1. It also relates to a kit for performing the method.
  • PCR polymerase chain reaction
  • PCR is suitable for the production of large quantities of a sought-after DNA sequence.
  • two synthetic oligonucleotide primers are added to a solution containing the sample, which are complementary to sections on a strand and a counter strand that flank the sought DNA sequence.
  • the DNA sequence searched for can be added after the amplification by adding detection reagents, e.g. by means of a color reaction or electrophoresis.
  • WO 94/02636 describes a method in which a first primer bound to a solid phase is brought into contact with and hybridized with a sample containing a nucleotide sequence. Subsequently, the sample vessel is opened and a second primer is added to the sample, the nucleotide sequence hybridizing. The second primer is marked. It accumulates on the solid phase. The marking can be observed there. Furthermore, it is known from WO 94/02636 to carry out a polymerase chain reaction using three primers in solution, the solution being brought into contact with the primers in succession.
  • WO 96/26291 describes a method for differentiating several alternative DNA sequences.
  • a first and a second primer are bound to a solid phase.
  • a third primer is in solution. This method is only suitable for distinguishing the predecessor from alternative DNA sequences, but not for the detection of a specific nucleotide sequence.
  • PCR only two primers are included in the reaction, one of which is bound to a solid phase. This is not very flexible and hard to access. The method is less suitable for PCR than if there are free primers.
  • a method for the detection of specific DNA is known from WO 90/11369, in which the sample is first subjected to a first amplification by means of PCR. The sample is then transferred to a further reaction vessel, where it is brought into contact with a second primer bound to a solid phase. A second amplification by means of PCR takes place.
  • This method also disadvantageously entails the risk of contamination when the sample is transferred from the first to the second reaction vessel.
  • the object of the invention is to eliminate the disadvantages of the prior art.
  • a fast method for the detection of a nucleotide sequence with a reduced risk of contamination is to be specified.
  • a method for the detection of a nucleotide sequence by means of polymerase chain reaction the nucleotide sequence being part of a solution consisting of a strand (S) and a counter strand (G) formed double-stranded nucleic acid molecule, with the following steps:
  • a) adding a first primer to the solution, the first primer being complementary to a first section of the strand located 5'-terminally of a central section, and a second primer, the second primer being complementary to a 5'-terminal second section the opposite strand is
  • the nucleotide sequence sought is thereby enriched on the solid phase.
  • the necessary reaction time is shortened and the sensitivity is improved.
  • the third primer is advantageously a DNA molecule or a PNA-DNA chimera.
  • the solid phase is a, preferably electrically conductive, plastic, the plastic being able to contain a polycarbonate, trimethylthiophene, triaminobenzene and / or a polycarbene and / or carbon fibers.
  • the solid phase is expediently a microtiter plate, in the cavity of which the third primer can be bound covalently or by means of biotin.
  • the nucleotide sequence when the nucleotide sequence is present, an interaction between a first and a second fluorophoric molecule that enables a radiation-free or direct energy transfer is generated or eliminated.
  • the first fluorophore molecule can be bound to the solid phase.
  • the first fluorophoric molecule may also be bound to the solid phase via the third primer.
  • a particularly simple variant consists in that the third primer has a hairpin loop, and the first fluorophoric molecule is bound to a first loop section and the second fluorophoric molecule opposite to a second loop section at a distance that enables the interaction.
  • the interaction can be eliminated by hybridization with a complementary strand complementary to the third primer or by a synthesis taking place at the third primer.
  • the second fluorophore molecule can be bound to the second primer.
  • the solid phase is expediently a microtiter plate.
  • the kit may comprise, as further components, the buffers required to carry out the polymerase chain reaction, the deoxy nucleotide triphosphates required to amplify the nucleotide sequence and the polymerase required to carry out the polymerase chain reaction, preferably a Taq polymerase.
  • the first and second primers and the further components can be in the lyophilized state.
  • a reaction can be started by adding the solution containing the nucleotide sequence.
  • the first and the second and / or the further components can be coated with wax. This enables the reaction to be started by heating the solution containing the nucleotide sequence and the coated components.
