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.

- 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.

- 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.
