Title:
核酸分析デバイス、及び核酸分析装置
Document Type and Number:
Japanese Patent JP5260339
Kind Code:
B2
Abstract:
An object of the present invention is to regularly align microparticles, on each of which a nucleic acid synthetase or a DNA probe capable of capturing a nucleic acid sample fragment is immobilized, on a support so as to improve throughput of nucleic acid analysis. The present invention relates to a method comprising immobilizing a nucleic acid synthetase, a DNA probe, or the like in advance to a microparticle, forming a pattern of metal pads each having a diameter smaller than the microparticle diameter with gold or the like on a support, and allowing a microparticle to be bound to the pads via a chemical bond. In addition, when the surfaces of microparticles are electrically charged, a pattern of metal pads each having a diameter equivalent to or larger than the microparticle diameter is formed with gold or the like on a support and a microparticle is allowed to be bound to the pads via a chemical bond. According to the present invention, many types of nucleic acid fragment samples can be regularly aligned at a high density and immobilized on a support. This allows high throughput analysis of nucleic acid samples. For example, if microparticles are immobilized at 1-micron pitches, a high density of 106 nucleic acid fragments/emm2 can be readily achieved.
