    摘要: In a nucleic acid isolation method for a solid biological sample, since two or more kinds of instruments are used for biological sample disruption and nucleic acid isolation, the operations are complicated, thereby increasing the operating labor, prolonging the operation time, and deteriorating the property of a nucleic acid associated with the prolonged operation time. A sample stuck to the instrument for disruption during the sample disruption operation is not brought to the subsequent nucleic acid isolation operation, thereby causing a problem of reducing the nucleic acid isolation efficiency. In the present nucleic acid isolation method, a step of disrupting a biological sample and a step of isolating a nucleic acid released from the disrupted sample are conducted with one instrument. The nucleic acid isolation efficiency can be improved without losing a sample stuck to an instrument for sample disruption, and the operability can be improved by simplifying the operations.

    摘要: It is an objective of the present invention to isolate RNA from a sample containing nucleic acid by safe and convenient operations. As a result of intensive studies, inventors of the present invention have found that DNA is precipitated out by adding an organic solvent to a mixed solution of a sample containing DNA and RNA and a chaotropic agent, so that RNA remains soluble. The present invention relates to a method whereby a sample containing nucleic acid, a chaotropic agent, and an organic solvent are mixed, DNA is precipitated out, and the precipitate is separated from the mixed solution, such that RNA is isolated from the residual solution. In addition, in accordance with the present invention, RNA is allowed to come into contact with a silica-containing solid phase so as to be bound to the silica-containing solid phase without the addition of a reagent or the like to the residual solution. Further, it is also possible to isolate DNA from the precipitate. In accordance with the present invention, high-purity RNA can be isolated from a sample containing DNA and RNA by safe and convenient operations. In addition, it is possible to simultaneously isolate RNA and DNA from a single sample.

    摘要: According to this invention, an instrument and a method for nucleic acid isolation is realized, whereby it is possible to prevent, for example, adherence of a discharged solution upon dispersion of such solution to the vicinity of a nucleic acid isolation column outlet.A light source unit and a light-receiving unit that receives totally reflected light of the photosensor 41 for detecting the fluid level are placed on a site on the side surface of the nucleic acid isolation column 35, where the photosensor can detect the fluid level corresponding to a remaining liquid volume of approximately 10 ul. In addition, the light source unit of the photosensor 41 is positioned in a manner such that incident light is totally reflected from the interface between the nucleic acid isolation column 35 and air in the nucleic acid isolation column 35 and light is allowed to be incident in the solution when reaching the interface between the nucleic acid isolation column 35 and the solution in the nucleic acid isolation column 35. The light-receiving unit of the photosensor 41 is positioned in a manner such that it receives the totally reflected light and is fixed on the upper part of the nucleic-acid-adsorptive solid phase 24. The fluid level detection sensor is in communication with a syringe-driving motor 34 via a control unit 40 such that a syringe 31 is driven upward when the fluid level reaches a predetermined level, provided that a certain volume of the liquid remains in the nucleic acid isolation column 35. Accordingly, dispersion of the dispersed liquid is prevented.

    摘要: It is an object of the present invention to release and isolate nucleic acid from a biological sample readily and in a short time. The present invention relates to a technique for isolating nucleic acid by which a biological sample including cells is caused to pass through a solid substance carrier to isolate the cells, a mixture of the cells and a cell lysis reagent is caused to pass through the solid substance carrier to disrupt the cells and release nucleic acid therein, and a mixture of the released nucleic acid and a nucleic acid binding reagent is caused to pass through the solid substance carrier to bind the nucleic acid to the solid substance carrier. Examples of an instrument comprising such solid substance carrier include an instrument comprising a syringe having a solid substance carrier fixed therein. The instrument is capable of moving a solution from one space to another space separated by the solid substance carrier, using pressurization and depressurization via the syringe, thereby causing the solution to pass through the solid substance carrier. Preferably, the solid substance carrier is a solid substance having a multitude of channels therein or a mesh-like solid substance composed of fibrous substances, by which cells are disrupted from a biological sample including the cells, nucleic acid is released, and the nucleic acid can be bound.
