| 摘要 |
<p>The invention relates to an improved protein and nucleic acid electrophoresis sequencer and a method for operating the same. Said sequencer carries out the operating method in an inert gas. The sequencer has the following structure: a dark chamber (1) with two electrodes (2)-(2') located on opposite poles; a gas intake (3) and injection of the aqueous sample by means of an electrospray (4); an electronic data acquisition system with a computer (6) and a direct current power source (7) with a double switch (8) to change the polarity of the electrodes. When a sequencer with radioactivity is used, the molecules are labeled with a radioisotope and reach the second electrode consisting of two plates (10)-(10'), the front plate having holes (11), and a scintillator (12) being placed in-between said plates to enable detection of the molecules by means of a photodetector (13) that supplies information to the computer (6). When no radioactivity is used, the second electrode is an electric gas detector (14).</p> |
