Full automatic instrument for extracting nucleic acids

Abstract

The invention discloses a full automatic instrument for extracting nucleic acids, which is capable of fully automating the processes of acquiring sample information, automatically adding samples, automatically loading consumptive materials, automatically monitoring the extraction process, and establishing a PCR reaction system. The full automatic instrument for extracting nucleic acids comprises a working platform, a sample adding system which is mounted on the working platform, a deep-well multiwell plate movement device and a nucleic acid extraction device, wherein a plurality of working positions are arranged on the working platform and comprise a sample area, a reagent area and an extract product storage area. The sample adding system respectively adds the sample and a PCR reaction reagent into the deep-well multiwell plate movement device and the extract product storage area from the sample area and the reagent area respectively, the sample is moved below the nucleic acid extraction device by the deep-well multiwell plate movement device and allowed to perform the nucleic acid extraction reaction, and the extraction products are stored in the extract product storage area. The impact of human factor on experimental result can be effectively reduced, and the purity the extracted nucleic acid and the nucleic acid extraction efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of nucleic acid extraction, in particular to a fully automatic nucleic acid extractor that realizes fully automated operations from sample information collection, automatic sample filling, automatic loading of consumables, automatic monitoring of the extraction process, and establishment of a PCR reaction system. Background technique [0002] Nucleic acid (ribonucleic acid RNA, deoxyribonucleic acid DNA) is the basic unit representing the genetic characteristics of living organisms. Nucleic acid detection is an advanced biological detection at the molecular level. Compared with traditional morphological detection, cytological detection, immunological detection, etc. With more obvious advantages such as sensitivity, specificity, and window-free period, nucleic acid detection has gradually been recognized as a standard gold standard method in recent years, and is widely used in major infectious diseases such as...

Problems solved by technology

At present, most inspection institutions adopt the method of manual experimental operation and semi-automatic extraction device. The extraction device only has a single function of magnetic bead movement, and the pretreatment of samples and reagents and the separation of extracted products are all done manually by the operator.

There are individual differences in manual operation, which not only affects the accuracy of the results, but also limits the throughput of the test when the number of samples is large
