Definitions
- the present invention relates to a method for amplifying DNA.
- asymmetric PCR method for example, a method in which the concentrations of the forward primer and the reverse primer are biased to each other (for example, see Non-Patent Document 1), the amplification ability of the RNA primer is higher than that of the DNA primer.
- DNA / RNA hybrid primers to take advantage of the difference in amplification ability between primers (see Non-Patent Document 2, for example).
- thermal asymmetric method using the difference see, for example, Non-Patent Document 3
- a method of using a blocker for DNA extension reaction to inhibit the extension reaction of one of the type II double-stranded DNAs to the single-stranded DNA for example, see Patent Documents 1 and 2.
- the second primer has a homologous base sequence on the ⁇ terminal side of the target sequence. That is, it has at least a part of the same base sequence in the same order from 5 ′ to 3 ′ as compared with the specific base sequence located at the ⁇ terminal side of the target sequence.
- the consensus sequence may be a sequence that can hybridize to the target sequence or a sequence complementary to the target sequence, or may be a sequence that cannot hybridize.
- a DNA polymerase activation step is performed under known conditions before the first process.
- PCR cycle (I) allows the first primer to be converted to a single-stranded DNA on one side of the type II double-stranded DNA on which the target sequence is present.
- Anneal D ⁇ .
- the region of the second primer that is homologous to the ⁇ -end of the target sequence is annealed to the other single-stranded DNA, and the DNA extension reaction with the first and second primers as starting points (5, terminal) proceeds. Then, an extended DNA strand starting from the second primer (5, end) and an extended DNA strand starting from the first primer are generated.
- the first primer 14 anneals to the single-stranded DNA on one side of the type II double-stranded DNA on which the target sequence 12 is present. I do. Also, the second primer 16 anneals to the other single-stranded DNA.
- a common sequence homologous to the ⁇ terminal side of the third primer exists at the ⁇ terminal side of the second primer or the first primer.
- a third primer having a high melting temperature with respect to the first and second primers and exhibiting an appropriate difference in melting temperature with respect to the first and second primers for example, the following method is used.
- a method of controlling Tm by binding a compound selected from a specific compound group and a specific base described below to the ⁇ terminal side of the third primer is also possible. Further, these methods may be combined.
- the Tm of the third primer can be more easily adjusted. Note that the specific base is
- the number of cycles of the PCR cycle (I) is 10 to 30 and the number of cycles of the PCR cycle ( ⁇ ) is 10 to 50. ! / ,.
