It is intended to provide a solid support capable of immobilizing nucleic acid molecules in a high proportion, and with a high bond strength to nucleic acid molecules. The solid support comprises a substrate and, provided thereon, an electrostatic layer for electrostatically attracting nucleic acid molecules and functional groups capable of covalently binding to nucleic acid molecules.

Solid support having electrostatic layer and use thereof

Provided is a light reflecting plate capable of reducing glare of reflected light while maintaining high light reflectance by regular reflection. The light reflecting plate includes a base, a light reflecting layer that is formed on the base and made of silver or silver alloy, or aluminum or aluminum alloy, in which arithmetic average roughness (Ra) is 0.10 to 0.30 &#x3bc;m and arithmetic average waviness (Wa) is 0.30 to 2.50 &#x3bc;m on a surface of the light reflecting layer.

It is intended to provide a method whereby DNA can be conveniently and rigidly immobilized on a substrate at such a high density as achieved by the conventional methods and a method of accurately detecting DNA. A substrate activation kit comprising a phosphate buffer (pH6), a solution A (an aqueous solution) of N-hydroxysuccinimide and a solution B (a dioxide solution) of 1-[3-(dimethylamino) propyl]3-ethylcarbodiimide; and a method of detecting DNA characterized by comprising spotting DNA on a substrate having been activated by using the above activation kit and then hybridizing the spotted DNA with fluorescence labeled DNA.
