Abstract: The present invention aims at easy and efficient selection of bands present on a lane. A region 502 is set on a display of a lane 503 having a plurality of bands 504 to 508, based on an input cursor 501 of a pointing unit. The bands 506 to 508 within the region 502 are displayed to be in a selection candidate state. The size of the region 502 may be altered by an input of a predetermined key of a keyboard. Along with the size alteration of the region 502, bands to be displayed in the selection candidate state also change. By selecting with the mouse button, a band of interest is accurately selected from the bands in the selection candidate state.

Abstract: A method for indexing and coding element information of at least one biological element provided on a microarray chip thereby identifying the microarray chip. Some of the element spots arranged on the microarray chip are used as index spots to be selectively provided with at a detective colorant. By doing so, the microarray chip is specified, and the element information as well as experimental information of the chip is automatically managed.

Abstract: The present invention provides a hybridization detection method capable of quantitatively determining the degree of the hybridization between a sample biopolymer and a probe biopolymer. In the method, the amount of a fluorescently labeled probe immobilized on a substrate as a spot is quantitatively determined by determining the fluorescence emitted from a fluorescent material labeling the probe, and the amount of a fluorescently labeled sample hybridized to the probe is quantitatively determined by determining the fluorescence emitted from the fluorescent material labeling the sample. The difference between the amount of the probe and the amount of the sample is normalized with the amount of the probe. Based on the normalized value, the amount of the sample hybridized to the probe can be determined relative to the amount of the probe spotted on the substrate.

Abstract: The apparatus for reading a luminescence pattern is equipped with a stage on which the sample to be read is mounted. A photoreceptor disk is installed in the lower part of the stage and scans and condenses light from the luminescent pattern of the sample at positions determined by the rotation of a rotary plate. A transport mechanism causes the stage and the photoreceptor disk to undergo relative motion. An optical guide part guides the light from the luminescent pattern to a photoelectric converter. The optical guide part may include mirrors or one or more optical fibers. The photoelectric converter converts the light into an electrical signal. A controller controls how scanning is performed by the photoreceptor disk and transport mechanism and generates a read scanning position signal. A data processor performs data processing by converting the electrical signal into a digital signal and obtains a scanning position signal from the controller.
