Abstract: There is provided a nucleic acid extraction method applicable to microbes in a relatively wide range, and capable of rapidly extracting nucleic acid. The nucleic acid extraction method comprises the steps of introducing a cell suspension into a vessel, sealing the vessel, and preheating a heater up to a set temperature not lower than 100° C. Further, the method comprises the step of bringing the vessel into contact with the heater heated up to the set temperature, thereby heating the cell suspension housed in the vessel up to a prescribed highest temperature at not lower than 100° C. with the vessel held in a sealed state.

Abstract: There is provided a method for preparing dendrimer-modified magnetic fine particles wherein such particles can be made within a shorter time and more inexpensively than in the above-stated prior art processes and lot-to-lot variations in properties are lessened. The method for preparing dendrimer-fixed magnetic fine particles comprises the steps of providing magnetic particles having a functional group at a surface thereof, providing a dendrimer having a functional group at a base end portion thereof and synthesized to a desired generation and binding the functional group of the magnetic particles and the functional group of the dendrimer directly or indirectly through a crosslinking agent.

Abstract: Dendrimer-coated magnetic fine particles comprise magnetic fine particles, a lipid bilayer covering a surface of individual magnetic fine particles, and a dendrimer bound to an outer layer of the lipid bilayer. With the dendrimer-coated magnetic fine particles, the dendrimer is positively charged are brought into contact with a nucleic acid-containing solution to adsorb the nucleic acid on the dendrimer, while the nucleic acid-adsorbed fine particles are collected by magnetic force to recover the nucleic acid from the solution.

Abstract: A chemical reaction cartridge enabling chemical reaction to be stably and safely carried out therein, and a method of using the same are provided. A chemical reaction cartridge is provided with a substrate, and an elastic member 2 overlaid on the substrate. A recess of a predetermined shape, depressed toward the top surface of the elastic member is formed in the back surface of the elastic member. The recess creates space between the substrate, and the elastic member, thereby making up a well, for holding the main ingredient of the epoxy adhesive, a flow path communicating with the well, a well for holding a curing agent for the epoxy adhesive, a flow path communicating with the well, a mixing part for mixing the main ingredient with the curing agent, and a discharge path for discharging a mixture. While the chemical reaction cartridge is not in use as yet, the flow paths, and the discharge path are closed, so that the wells are, in effect, in a hermetically sealed condition.
