Device for quickly extracting DNA through transferring magnetic beads

Abstract

The invention relates to a device for quickly extracting DNA through transferring magnetic beads. A supporting seat is arranged under an extracting machine head and an anti-fouling plate, the extracting machine head is connected with the supporting seat through an X-direction drive belt, and the X-direction drive belt drives the extracting machine head to do reciprocating motion in the X direction; a magnetic rod assembly is arranged above a magnetic rod sleeve frame, is connected with the extracting machine head through a Z-direction slide rail, does reciprocating motion in the Z direction and extends into or moved out of the magnetic rod sleeve frame; the magnetic rod sleeve frame is connected with the Z-direction slide rail; the anti-fouling plate penetrates through a first Y-directionchute and is connected with a first Y-direction drive belt; a deep hole plate carrying frame is arranged at the upper end of the supporting seat and is connected with a second Y-direction drive belt through a second Y-direction chute; a deep hole plate fixing block drives the deep hole plate carrying frame to move in or out of the lower part of the anti-fouling plate; a deep hole plate is arrangedat the upper end of the deep hole plate carrying frame and is fixed by the deep hole plate fixing block. The device provided by the invention is simple to operate, short in used time, reliable in extraction mode, capable of effectively preventing cross contamination and high in degree of integration.

Description

technical field [0001] The invention relates to a device for extracting DNA, in particular to a device for quickly extracting DNA by transferring magnetic beads. Background technique [0002] Since the birth of Watson-Crick's DNA double helix model, biology has entered a new era. In the field of biology, whether it is the detection of pathogenic microorganisms, species identification, or the origin of species, diversity assessment and their relatives The research on relationships, system evolution, etc., all need to separate and purify nucleic acid first, so the extraction of DNA has become the basis for scientific research in all disciplines in the fields of biomedicine and even agriculture, forestry, animal husbandry and fishery. Whether high-quality nucleic acid can be extracted is the key to nucleic acid molecular biology experiments, and the sensitivity and specificity of the extraction method will also directly affect the success or failure of subsequent experiments. ...

AI Technical Summary

Problems solved by technology

The operation of the existing device is complicated, the cost is high, and the time-consuming is long. During the process of transferring the magnetic beads, the sample is easily contaminated, and the shaking and heating cannot be completed, which seriously affects the efficiency of DNA extraction.
