Abstract

The invention relates to the technical field of nucleic acid extraction, and particularly discloses a nucleic acid extraction device for molecular diagnosis, which comprises a base and two sliding seats which are adjustable on the base with front and rear longitudinal positions, each of the sliding seats is fixedly placed with a cup body by a clamping assembly, and each of the lower part of the cup body is rotatably provided with a rotating disc having a plurality of protrusions on the upper surface thereof; the plurality of electromagnetic rods are uniformly arranged on a bottom surface of anelectromagnetic rod mounting bracket; the electromagnetic rod mounting bracket is detachably mounted on an electromagnetic rod mounting seat by a mounting bolt, and the electromagnetic rod mounting seat is installed at a bottom end of a lifting assembly. According to the nucleic acid extraction device provided by the embodiment of the present invention, the electromagnetic rod is placed in one ofthe cups by the lifting assembly, the nucleic acid is pasted by the electromagnetic rod, and the electromagnetic rod adsorbs the magnetic beads to which the nucleic acid is adhered, which facilitatesthe next extraction work.

Description

technical field [0001] The invention relates to the technical field of nucleic acid extraction, in particular to a nucleic acid extraction device for molecular diagnosis. Background technique [0002] Common methods for nucleic acid extraction include the magnetic bead method and the concentrated salt method. The magnetic bead method uses nanotechnology to improve and modify the surface of superparamagnetic nanoparticles to prepare superparamagnetic silica nano-magnetic beads. It can specifically recognize and efficiently combine with nucleic acid molecules on the microscopic interface. Using the superparamagnetism of silicon oxide nanospheres, under the action of Chaotropic salt and an external magnetic field, it can extract samples from blood, animal tissues, food, pathogenic microorganisms, etc. It can be used in many fields such as clinical disease diagnosis, blood transfusion safety, forensic identification, environmental microbial detection, food safety detection, and ...
