摘要:
When multiple kinds of bacterial colonies are present in a petri dish and, for example, a drug tolerance is to be measured, harvesting of mixed colonies of different types of bacteria makes it impossible to accurately determine the drug tolerance. Also, it is required to improve the throughput of a device for harvesting a bacterial colony. From images illuminated from multiple directions, isolating bacterial colonies are automatically extracted. Next, the image feature amounts are calculated from the multiple images that are illuminated from multiple directions and colonies are grouped depending on the feature amounts. Then, bacterial colonies to be harvested are determined based on the results of the grouping.

At a wall constituting a space for a thermostatic oven in an electrophoresis apparatus, a capillary array attachment portion is formed which permits attachment of a plurality of capillary arrays having different length. Thereby, a selected capillary array constituted by collecting a plurality of capillaries can be easily attached to the electrophoresis apparatus depending on measurement purpose.

Disclosed is a wafer inspecting apparatus suitable to determine whether a scattering substance is a surface foreign matter or an internal defect even if the particle size of the scattering substance is smaller than the wavelength of irradiation rays used for inspection. The wafer is obliquely irradiated with irradiation rays at the Brewster angle, and scattered rays which are scattered from a scattering substance on or in the wafer are detected at and angle 0° and an angle of the Brewster angle or more by detectors. Then, it is determined whether the scattering substance is a surface foreign matter or an internal defect on the basis of a ratio between the intensities of the scattered rays detected by the detectors. The intensity of scattered rays which are scattered from a surface foreign matter and detected at an angle of the Brewster angle or more is larger than the intensity of scattered rays which are scattered from the foreign matter and detected at an angle 0°, and the intensity of scattered rays which are scattered from an internal defect and detected at an angle of the Brewster angle or more is smaller than the intensity of scattered rays which are scattered from the internal defect and detected at an angle 0°. This makes it possible to distinguish the surface foreign matter and the internal defect from each other.

A convenient method for nucleic acid analysis is provided, which enables 1000 or more types of nucleic acid to be analyzed collectively with high comprehensiveness and with a dynamic range of at least four digits. In particular, provided is a very effective analytical method especially for untranslated RNAs and microRNAs, of which the types of target nucleic acids is 10000 or lower. Nucleic acids can be analyzed conveniently and rapidly with high comprehensiveness and quantitative performance at single-molecule sensitivity and resolution by following the steps of: preparing a group of target nucleic acid fragments one molecule at a time and hybridizing the nucleic acid molecules, which have known base sequences and have been labeled with the fluorescence substances, with the group of the target nucleic acid fragments to detect the fluorescence substances labeling the hybridized nucleic acid molecules.

To be adapted to various types of latex reagents for detecting scattered light and thereby measuring agglutination reactions with high sensitivity while sufficiently ensuring integration time. To be adapted to various types of latex particles of different particle sizes, a plurality of light receivers are arranged in a plane perpendicular to the direction of cell movement by rotation of a cell disk. To ensure sufficient integration time, the angle between the optical axis of the irradiation light and each of a plurality of optical axes of scattered light viewed from above the cell is made equal to or less than 17.7° including a mounting error.
摘要:
An apparatus measures individual measurement sites on a DNA chip in a short period of time. The DNA chip is irradiated by light-emitting diodes (LEDs) so as to excite fluorescent dye at each measurement site, and fluorescence emitted from the individual measurement sites is detected all at once. Since substantially uniform measurement conditions can be obtained for each measurement site, measurement accuracy increases. The read mechanism requires less space and is less costly, thereby decreasing the failure rate and virtually eliminating the need for maintenance of the apparatus.
