<P>PROBLEM TO BE SOLVED: To provide a fluorescence emission reading apparatus capable of detecting the fluorescence emission image of a gel for migration with high quality, even if gels are not uniform or an impurity is mixed or even through the use of the gel for migration having a low transparency. <P>SOLUTION: The fluorescence reading apparatus is constituted of the gel 1 for migration in which sample fragments having molecular weight separated by electrophoresis and labelled with fluorescence are distributed, a gel cassette 7 for holding the gel 1 for migration, a semiconductor laser 2 for exciting fluorescent substances, a resonant scanner 4 (scanning device) for scanning a side surface of the gel 1 for migration in one axial direction with exciting light from a semiconductor laser 2, a diffuser 5 for diffusing in the direction of an optical axis the exciting light used for scanning in the axial direction between the resonant scanner 4 and the gel 1 for migration, a CCD camera 3 (fluorescence detector) for detecting fluorescence of the gel 1 for migration, and a detecting filter 6 for transmitting only the fluorescence by cutting the exciting light between the gel 1 for migration and the CCD camera 3. <P>COPYRIGHT: (C)2004,JPO |
