The invention relates to a linear movement type reaction treatment apparatus and a method thereof, and an object thereof is to reliably prevent cross-contamination and to decrease a working time or a working space involved with reaction treatment. A linear movement type reaction treatment apparatus includes: a container group in which one or two or more reaction containers and two or more liquid storage portions are arranged in at least one linear shape; a dispensing head to which one or two or more dispensing tips suctioning and ejecting a liquid through a front end insertable into the reaction containers and the liquid storage portions are detachably attached and which is relatively movable between the dispensing tip and the container group in a linear arrangement direction; a magnetic portion which is provided in the dispensing head and is capable of separating magnetic particles contained in a solution inside each dispensing tip by applying a magnetic field into each dispensing tip so that the magnetic particles are adsorbed to an inner wall of the dispensing tip and of separating the adsorbed magnetic particles by removing the magnetic field therefrom so that the magnetic particles are resuspended in the solution ; and an ultrasonic vibration device which applies an ultrasonic vibration to a sample storage portion, as sample storage portion at least one of the liquid storage portions are selected.
Abstract:
The disclosed device for trapping biologically-relevant substances can easily collect biologically-relevant substances from a thin tissue section or a gel in which said biologically-relevant substance have been fractionated. Said device is provided with: trapping bodies for trapping biologically-relevant substances; carriers that hold the trapping bodies; and electrodes for charging the trapping bodies. The trapping bodies are charged and brought into contact with a prescribed position on a thin tissue section that contains biologically-relevant substances or a gel in which biologically-relevant substances have been fractionated, thereby trapping said biologically-relevant substances from said gel or thin tissue section.
