Apparatus for determining base sequence
First Claim
1. An apparatus for determining a base sequence comprising an assembly for making an exciting beam incident on a surface of a slab of electrophoretic gel in a direction normal to said surface, the gel containing nucleic acid fragments labeled with a labeling pigment and developed or being developed therein by electrophoresis;
- means for concentrating said exciting beam on said gel;
means for scanning said surface of said gel with said exciting beam; and
a light receiving unit for receiving at an end face of said gel the luminescence emitted by said labeling pigment on the fragments developed in said gel.
