- DNA chip method a new analysis method or methodology called the DNA microarray method
- these methods are basically the same as conventional methods in that they are nucleic acid detection and quantification methods based on the hybridization reaction between nucleic acids / nucleic acids. It can also be applied to the detection and quantification of proteins and sugar chains based on interchain and between sugar chains / proteins.
- the major feature of these techniques is that a large number of DNA fragments, proteins, and sugar chains are aligned and immobilized on a glass flat substrate piece called a microarray or chip.
- microarray method examples include, for example, the expression of genes in A method in which a sample labeled with an element or the like is hybridized on a piece of a flat substrate, mutually complementary nucleic acids (DNA or RNA) are bound to each other, and the site is read at high speed by a high-resolution analyzer, There is a method of detecting a response such as a current value based on a chemical reaction. Thus, the amount of each gene in the sample can be quickly estimated.
- a technique for immobilizing nucleic acids on a substrate such as a method for immobilizing nucleic acid on a flat substrate such as slide glass.
- a method is disclosed in which lysine, aminosilane, or the like is coated, and each nucleic acid is immobilized using a spotter called a spotter.
- a nucleic acid probe (a nucleic acid immobilized on a substrate) used in a DNA chip is a conventional one.

That is, 1) When hybridization is performed, the sample DNA is easily non-specifically adsorbed to the area other than the spot where the probe DNA is immobilized because the glass is hydrophilic, and fluorescence is emitted by a device called a scanner. When performing detection, this non-specifically adsorbed sample is also detected and noise is increased.2) Since the glass is rigid, the spatial freedom of oligo DNA covalently bonded to it is hindered. For this reason, there was a problem that the hybridization efficiency with the sample DNA was low, the signal intensity was low, and as a result, the S / N ratio was not sufficient.
- the problem to be solved by the present invention is to provide a carrier in which DNA is immobilized firmly on a resin substrate with high hybridization efficiency. Further, the present invention provides a carrier on which a selective binding substance having high detection sensitivity is immobilized while preventing deterioration of SZN as described above.

For this reason, it is possible to obtain a carrier having high hybridization efficiency with the specimen.
- the advantage of having a high degree of freedom is that especially when the immobilized selective binding substance is oligo DNA, which is a DNA with a base length of 10 to 100 bases and a target, it can be used for hybridization with the sample. It provides excellent properties such that the efficiency of dicing is greatly improved.
- a carrier is made of a polymer containing a structural unit represented by the general formula (1), finer particles can be obtained by using an injection molding method or a hot-emboss method than glass, ceramic, metal, or the like. It is possible to easily mass-produce carriers having various shapes. Thus, the shape of the carrier on which the selective binding substance is immobilized will be described.
- the carrier on which the selective binding substance of the present invention is immobilized has an uneven portion, and it is preferable that the selective compatible substance is immobilized on the upper surface of the convex portion.
- the S / N is a better selective binding substance.
- the height of the plurality of protrusions of the uneven portion it is preferable that the height of the upper surface of the protrusion be substantially the same.
- the selective binding substance is immobilized on the surface of the convex part with a slightly different height, this is reacted with the fluorescently labeled analyte, and then scanned with a scanner. In this case, the height at which the difference in signal level intensity does not matter.
- the heights are substantially the same when the height difference is smaller than 100 m.

- the upper surface of the projection is substantially flat means that there is no unevenness of 50 m or more.
- the height of the upper surface of the convex portion of the uneven portion and the height of the flat portion are substantially the same.

This focused light is illuminated on the surface of the microarray, and the laser light is focused on the surface of the microarray. And of this condition By scanning the objective lens or the microarray itself, the fluorescence generated from the microarray is read.
- the fluorescence (noise) of the sample DNA non-specifically adsorbed to the concave portion of the concave and convex portion is detected. It has the effect of being hard. The reason for this is that the laser beam is deformed in the concave portion because the laser light is focused on the upper surface of the concave portion. Conversely, the difference between the height of the highest convex surface and the height of the lowest convex surface among the multiple convexities on which the selective binding substance is immobilized is 50 ⁇ or less.

- the selective binding substance is immobilized only on the upper surface of the convex portion of the uneven portion, instead of spotting the selective binding substance on the flat carrier. Therefore, even if the sample sample is non-specifically adsorbed to the portion other than the upper surface of the convex portion, the focus of the excitation light is blurred at the portion other than the upper surface of the convex portion. No fluorescence is detected. For this reason, noise is reduced, and as a result, SZN is improved.

- Comparative Example 4 A 1 mm thick plate (Zeklon, manufactured by Mitsui Chemicals, Inc.) containing polyacrylonitrile as a main component was cut into a size of 75 mm ⁇ 25 mm. This was immersed in 10 N NaOH and left at 70 ° for 12 hours. After washing, immobilization of the probe DNA (probe DNA has a base length of 60 bases) and hybridization with the sample DNA were performed in the same manner as in Example 1. As a result of measurement in the same manner as in Example 1, autofluorescence was large, and it was impossible to detect the presence or absence of hybridization between the sample and the probe. This is because the plate itself is yellowish and the autofluorescence is very large.

- methacrylic acid methacrylic acid
- a 1 mm thick plate made of a polymer obtained by copolymerizing 99 parts by weight of methyl methacrylate (MMA) and 1 part by weight of methacrylic acid was prepared by a casting method. Alkaline treatment was performed using Gene Pix 400 B from Ruments at excitation wavelength of 532 nm, gain setting of photomultiplier of 700 and laser power of 33%. When the plate of the embodiment was measured, the autofluorescence intensity of this plate was 850.
- Example 2 The same experiment as in Example 1 was performed except that the heat treatment (soaking in sodium hydroxide) was omitted. As a result, no fluorescence indicative of hybridization was observed. This is considered to be because carboxyl groups are not sufficiently generated unless surface treatment with an alkali-treated product or acid is performed, and as a result, the amount of probe DNA immobilized is extremely small. Industrial applicability
- a carrier on which a selective binding substance having a good S / N ratio is immobilized which has a low non-specific sample adsorption, a good hybridization efficiency, and a good S / N ratio. be able to.
