Abstract
In the multi-color fluorescence detection type electrophoresis apparatus provided with the electrophoresis gel plate, excitation laser source, means to separate the fluorescence images according to each emission wavelength, and the detector of the fluorescence subjected to wavelength selection, two or more laser sources are provided, each of laser lights is irradiated on the sample on a time-sharing basis, and the filter which cuts off the scattered light of each the laser synchronous with the laser beam is installed in front of the wavelength separation means thereby providing simultaneous, quick and real-time analysis of a great number of samples such as DNA and RNA labeled by many types of fluorophores, without overlapping the wavelengths of the excitation light and the fluorescence.
