Abstract
The present invention detects and quantities only specific hybridization bindings. A biochip which is spotted with a plurality of probe biopolymers is accommodated in a container into which a washing solution is supplied from a liquid supplying unit . A heat block controls the temperature of the biochip according to a predetermined time pattern. A pickup unit picks up an image of the spot surface of the biochip at predetermined pickup intervals. The plurality of images picked up with the pickup unit are stored in a computer . By analyzing the images for individual spots, hybridization can be detected with high reliability for every spots without being influenced by optimal hybridization temperatures which differ depending upon the types of probes on the spots.
