ABSTRACT:
In a wavelength dispersion electrophoresis apparatus which detects fluorescences of unequal wavelengths emitted from the samples of DNA, RNA or the like labeled with a plurality of fluorophores, a direct-vision prism (14) is interposed between a two-dimensional fluorescence detector (7) and an electrophoretic plate (17) in order to separate and discriminate the emission wavelengths of the respective fluorophores. The direct-vision prism (14) is disposed for the wavelength dispersion of the fluorescences in this manner, whereby the fluorescences of the individual wavelengths can be separated and detected at a high sensitivity by a simple mechanism and without distorting a fluorescence image.
