Full-automatic nucleic acid extraction system

Abstract

The invention relates to the field of biotechnology equipment, and provides a full-automatic nucleic acid extraction system. The full-automatic nucleic acid extraction system comprises a mounting seat, a syringe assembly, an extraction platform assembly, a magnetic separating assembly, a reagent kit and a driving assembly, wherein the syringe assembly and the extraction platform assembly are in sliding connection with the mounting seat; the syringe assembly is located above the extracting platform assembly; the reagent kit is loaded on the extraction platform assembly; the driving assembly isused for driving the extraction platform assembly to move back and forth and complete the motion of operation positioning; the magnetic separating assembly is mounted on the extraction platform assembly and moves along with the extraction platform assembly; the driving assembly is used for driving the syringe assembly to move up and down and complete the motions of puncturing an encapsulating film, taking / removing a pipetting head or sucking / discharging liquid; and the driving assembly is used for driving the magnetic separating assembly to move up and down and complete the motion of separating magnetic beads. The full-automatic nucleic acid extraction system disclosed by the invention is accurate in liquid sucking and discharging control and short in experiment flow time, and can sufficiently guarantee the validity of the experiment result.

Description

Technical field [0001] The invention relates to the field of biotechnology equipment, and more specifically to a fully automatic nucleic acid extraction system. Background technique [0002] In the research fields of genetic engineering and protein engineering technology, nucleic acid molecules are the main research objects. Since nucleic acids exist in cells in a state that is bound to proteins, as the pre-processing work of nucleic acid analysis, nucleic acid extraction is the basic technology of nucleic acid research. The purpose of nucleic acid extraction is to remove proteins, polysaccharides, lipids and other biological macromolecules that are bound to nucleic acids. At present, the main nucleic acid extraction method is the magnetic bead method. Magnetic beads are magnetic particles used for nucleic acid separation and must have superparamagnetic properties and surface Functional groups have these two characteristics. First, the superparamagnetism ensures that the aggrega...

Problems solved by technology

Nucleic acid extraction requires precise positioning and fine operation during the operation process. The automatic nucleic acid extraction instrument must be a precise instrument, and the cooperation between the various transmission connection parts must be strict and meticulous. However, the transmission parts in some nucleic acid extraction instruments currently on the market use The connection of flexible parts such as springs will obviously reduce the accuracy of the transmission
