Abstract:
A cell lysis device for lysing cells or viruses, comprising a cell lysis tube having a sample inlet; a pump connected to the cell lysis tube for transferring a sample into the tube; a sealing unit for reversibly sealing a specific region of the tube; and a laser source for generating a laser is provide. Further, a method of lysing cells or viruses using the cell lysis device is provide. The method comprises introducing a sample containing cells or viruses and optionally magnetic beads to the cell lysis tube through the sample inlet; transferring the sample to a specific region in the cell lysis tube by means of the pump; temporarily sealing the region of the cell lysis tube where the sample is placed with the sealing unit; irradiating the sample with the laser; removing the sealing unit from the cell lysis tube; and discharging the sample from the cell lysis tube by means of the pump.

Disclosed is a method for detecting nucleic acid hybridization by using intercalator binding to hybridized nucleic acid, wherein oxidation-reduction of transition metallic complex is induced to cause electrochemiluminescence, thereby providing a method for detecting nucleic acid hybridization without a special labeling.
Abstract:
A multi-channel fluorescence measuring optical system and a multi-channel fluorescence sample analyzer using the optical system are provided. The multi-channel fluorescence measuring optical system, which irradiates light onto a plurality of sample channels and detecting fluorescence radiated from samples, includes: a light source; an integrator for giving the light irradiated from the light source a uniform intensity distribution; a sample holder having a plurality of sample channels on which the samples are mounted, wherein the samples are exited by the light emitted from the integrator; and a beam splitter between the integrator and the sample holder for dividing the incident light in a predetermined ratio. Since the light intensities of fluorescence images are detected using optical fiber bundles and photodiodes, the manufacturing cost can be greatly reduced, and the optical system can be miniaturized.
Abstract:
The present invention provides a biochip which includes: a substrate having a center hole at a central portion, an biomaterial region aranged at a circumferential portion of the top surface of the substrate; and an information region formed on the substrate between the biomaterial region and the center hole and having the information on the biomaterials. In the method for detecting biomaterials using the biochip, a disk-type upper substrate is placed on the top surface of the biochip, a sample is put between the disk-type upper substrate and the biochip, the reaction between the sample solution and the biomaterial of the biochip is accelerated by rotating the biochip, and the detection unit analyzes the biomaterial by receiving the light emitted from the biomaterials, thereby making it possible to analyze the biomaterial of the sample solution. Since the biochip of the present invention is constructed as a disk type, high-priced scanning equipment is not necessary for thereby reducing the cost for detecting biomaterials. Since the sample solution is stirred by rotating the biochip, the speed of binding reaction is increased for thereby decreasing the time for analysis. Since the information on the biomaterial and the analytical information of the biomaterial can be recorded in the biochip, the management of the information of the biomaterials is made easier.
