Description

technical field

[0001] The invention relates to the technical field of nucleic acid extraction, in particular to a nucleic acid extraction device and a working method thereof. Background technique

[0002] Nucleic acid is the basic object of molecular biology research, and the nucleic acid extraction step is the most important and basic link in molecular diagnosis. There are many methods to extract DNA or RNA from biological samples, such as traditional organic solvent extraction method, silica gel molded column adsorption method, magnetic bead separation method and charge method, etc. Among them, the magnetic bead separation method is currently the most widely used method with the most mature automation conditions. The basic principle is to use the surface of small particles with magnetic materials to make them adsorb the required substances through certain treatments, and then enrich them by magnet adsorption. Finally, the waste liquid is discarded, and the enriched magne...
