Abstract

The invention discloses a capillary electrophoresis apparatus. The capillary electrophoresis apparatus comprises a shell unit; a containing cavity is formed in the shell unit; a bracket unit is arranged in the containing cavity; a clamping unit is arranged on the bracket unit; a clamping door is arranged at the position, corresponding to the clamping unit, of the shell unit; the clamping unit canbe replaced through the clamping door; a capillary assembly is arranged in the clamping unit; a sample loading unit is arranged at the position, corresponding to the cathode end of the capillary assembly, of the bracket unit; a sample loading door is arranged at the position, corresponding to the sample loading unit, of the shell unit; and the sample loading unit can replace samples through the sample loading door. According to the capillary electrophoresis system, the clamping unit, the sample loading unit, an optical detection unit and other components are integrated together, and therefore,the system is high in automation degree and can meet increasingly high requirements for the miniaturization, integration and convenience of detection equipment.

Description

technical field [0001] The invention relates to the field of biochemical detection, in particular to an integrated automatic capillary electrophoresis instrument. Background technique [0002] Capillary electrophoresis uses a quartz capillary as a separation channel, a high-voltage direct current electric field as a driving force, and a porous gel as a supporting medium. When the size of a DNA molecule is equivalent to the pore size of the gel, its mobility is related to its size. Less hindrance results in faster surge from the capillary, longer fragments are more hindered and slower to surge from the capillary. Because the DNA molecules are negatively charged, after the DC high voltage is applied to both ends of the capillary, the DNA labeled with the fluorescent group will enter the capillary from the cathode port of the capillary and surge towards the anode, and DNA molecules of different lengths will pass through the detection window successively. When a DNA molecule pa...
