- cDNA 0.005 ⁇ g / ⁇ ⁇ , 5 ⁇ primer set, 50 U / ⁇ 1 Taq DNA polymerase, supermidine 100 mM, 0.1 M trehalose, 250 mM Tris-HCl (pH 8.3), 1.25 M KC1, 132.5 mM MgCl, and 5 M were adjusted to each dNTP.
- PCR was performed under the following conditions.
- Lane 17 shows the results.
- Lanes 1 and 2 are samples in which cDNA, primers, polymerase, spermidine, a type of polyamine as a reaction promoter, and a PCR buffer composition were immobilized on 60MDP paper.
- Lane3 is a sample in which the composition excluding spermidine alone is fixed. In both cases, it was found that the immobilized DNA can be amplified by adding water, and the amplification reaction was accelerated in the sample in which the reaction accelerator was immobilized.
- the support of the present invention can be used for storage and distribution of enzymes. It can also be applied to printed materials and reagent kits.
- SEQ ID NO: 1 shows the nucleotide sequence of Primer-21M13.
- SEQ ID NO: 2 shows the nucleotide sequence of primer 1233-Rv.

- SEQ ID NO: 4 shows the nucleotide sequence of primer HsLHIF.
- SEQ ID NO: 5 shows the nucleotide sequence of primer HsLHIR.
- SEQ ID NO: 6 shows the nucleotide sequence of primer HsLH2F.
- SEQ ID NO: 7 shows the nucleotide sequence of primer HsLH2R.
- SEQ ID NO: 8 shows the nucleotide sequence of aptamer for Taq DNA polymerase.
- SEQ ID NO: 9 shows the nucleotide sequence of mouse isoquinate dehydrogenase (NADP) cDNA.
- SEQ ID NO: 10 shows the nucleotide sequence of mouse isoquenate dehydrogenase (NAD) cDNA.
- SEQ ID NO: 11 2 shows the nucleotide sequence of the cDNA of oxodaltalate dehydrogenase.
