Abstract
A multi-colored electrophoresis pattern reading apparatus is capable of labelling each of plural samples separately with each of plural fluorescent substances having different fluorescence wavelengths, by electrophoresing the plural samples to develop a pattern, exciting the fluorescent substances labelled on the samples to emit fluorescence, and reading a fluorescent pattern emitting the fluorescence. The apparatus contains a source for the light for exciting the fluorescent substances; a light scanning mechanism for scanning the light to irradiate a gel in the direction of its thickness with the light; a light receiving section for receiving fluorescence resulting from the light source separated from the scattered light resulting from a reading surface on the basis of a spatial position relationship of a light receiving path by setting a light receiving surface in a direction different from an optical axis of the irradiating light; an optical filter section for separating the resulting optical signals section into plural wavelengths; an optoelectric conversion section for converting optical signals into electrical signals; and an amplifier for amplifying the electrical signals by an integrating operation corresponding to scanning of the irradiating light, and for generating electrical signals indicative of fluorescence from the pattern one after another.
