Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
73 words
A fluorescence detection type electrophoresis apparatus for determining base sequence of a sample, comprising an electrophoresis separation device (30) for electrophoresis-separating said sample (32) labelled with fluorescence, an excitation light source (31) for exciting said sample, and a detection means (33) for detecting the fluorescence emitted by said sample that is excited, wherein a gel plate (4) having a polyacrylamide concentration of 2 to about 6% is used as said electrophoresis separation device.
