Abstract
An electrophoretic apparatus according to this invention comprises electrophoretic paths along which sample fragments labeled with phosphor migrate; electrodes disposed at both the ends of said electrophoretic paths; a driving power source for giving said sample fragments on the electrophoretic paths electrophoretic force by applying an electric potential difference between said electrodes; an excitation light source projecting an excitation light to said sample fragments on said electrophoretic paths; and means for detecting fluorescence emitted by the phosphor existing in the sample fragments and excited by the excitation light. Said an excitation light source is so disposed that the excitation light is projected to said sample fragments on said electrophoretic paths in a direction substantially parallel to a plane containing said electrophoretic paths.
