Double row nucleic acid extraction box suitable for nucleic acid diagnostic system

Abstract

The invention discloses a dual-row nucleic acid extraction box suitable for a nucleic acid diagnostic system. The box comprises a box body. The left end and the right end of the box body are each provided with a guiding groove. A disconnecting prevention plate is arranged on the front side of the box body. A first partition plate and a second partition plate are arranged on a base plate of the box body in a spaced mode in the longitudinal direction. The box body is partitioned into a purified product storage area, a reagent storage area and a reaction area through the first partition plate and the second partition plate. Dual-row arrangement is adopted, space is saved, and the requirement for a small nucleic acid isolation machine is met; an upper purified pipe, an upper reagent bin opening and an upper reaction bin opening are distributed in a stepped mode, the purified product storage area, the reagent storage area and the reaction area are partitioned, and samples are prevented from being polluted; a puncture device can puncture sealing films on two reagent bins at the same time, and the working efficiency can be improved; the lower portions of the reagent bins are of an inverted cone structure, and the useless reagent dosage inside the reagent bins is minimized; the reaction bin is separated from first and second spear bins, an enrichment device is placed at the lower portion of the reaction bin conveniently, and the enrichment rate can be increased.

Description

technical field [0001] The present invention relates to an extraction cassette for a nucleic acid diagnosis system, in particular to a double-row nucleic acid extraction cassette suitable for a nucleic acid diagnosis system. Background technique [0002] Polymerase chain reaction (ie Polymerase Chain Reaction, PCR for short) is a molecular biology technique used to amplify specific DNA fragments. The PCR reaction can specifically amplify a very small amount of DNA millions of times, thereby greatly improving the analysis and detection capabilities of DNA molecules. At present, the key factor leading to the failure of the PCR reaction is the loss or contamination of the target DNA due to the uncontrolled purification quality. Therefore, the purification of the target DNA after replication is a key operation that directly affects the gene amplification reaction and directly affects the accuracy of disease detection results. The nucleic acid extraction box used in the PCR puri...

Problems solved by technology

In the existing nucleic acid extraction box, it is necessary to puncture the sealing film on the extraction box one by one, which affects the work efficiency; the reaction chamber of the existing nucleic acid extraction box is mixed unevenly and takes a long time, which affects the purification efficiency; there is only one tip chamber on the box body , inconvenient to use
