Hand-held electrophoresis detecting apparatus and electrophoresis separation and analysing system using said apparatus

Abstract

The detection device comprises the body and the detachable box including at least one detector tube column. The analytic system comprises the host instrument and the handhold electrophoresis detection device. The host instrument controls the process for testing the sample. The handhold electrophoresis detection device can connect to the host instrument in detachable manner electrically. The detector tube column possesses the first end and the second end. The first voltage can be applied to the first end and the second voltage can be applied to the second end. With the sample being attached to the detector tube column, based on the difference between the first voltage and the second voltage, the sample is moved from the second end to the first end in the detector tube column.

Description

technical field [0001] The invention relates to an electrophoresis separation and analysis system, in particular to an electrophoresis separation and analysis system with a hand-held electrophoresis detection device. Background technique [0002] Generally, the test method using electrophoretic separation is to use electrophoretic separation to analyze and test the difference between the ratio of molecular charge and molecular weight, molecular weight or sample structure, especially in molecular biology. It is often used for the analysis of substances such as nucleic acids and proteins. It is a powerful tool for testing gene fragment molecules. [0003] The basic electrophoresis system is mainly composed of a high-voltage power supply, a separation column or film, and a control circuit. figure 1 It is a schematic diagram of an existing electrophoresis system, wherein the existing flat plate electrophoresis system 10 represented has a separation tank 11 and a power supply 12...

Problems solved by technology

[0008] However, if microcapillary electrophoresis or microcapillary electrophoresis chip equipment is used, although it has the advantage of high resolution, the instrument is expensive and complicated, so it is only used in occasions requiring precise analysis; in addition, the use and maintenance of its equipment is not convenient, Moreover, its instruments and consumables are expensive. In general molecular biology laboratories, they are limited to the sequencing of gene sequences and cannot be widely used in general molecular biology research and analysis.

[0009] In addition, whether it is a flat plate electrophoresis system or a microcapillary electrophoresis system, the entire system is a whole, so that the detection needs to be limited within a certain range, which reduces the mobility of the detection

[0010] In addition, whether it is a flat plate electrophoresis system or a microcapillary electrophoresis system, before testing, the sample needs to be transferred from a sample storage tank to the electrophoresis system, that is, two steps are required for detection, which increases the complexity of the detection operation. time and bring some inconvenience to the research operation
