DNA extraction kit

Abstract

The invention relates to the field of kits, and particularly discloses a DNA extraction kit. The DNA extraction kit comprises a kit body, a rotating structure, a fixing structure, a clamping structure, a freezing structure, a drawing structure and a moving structure. The rotating structure is installed inside the kit body, so that the sealing protection effect on the kit body can be achieved, and it can be ensured that a test tube placed inside the kit body is always in a vertical state, thus, the circumstance that the test tube leaks liquid when the kit body is transported can be avoided, and the transportation safety of reagents is greatly improved; in cooperation with the freezing structure installed inside the kit body, the refrigeration effect on the reagents placed inside the kit body can be achieved, water drops condensed outside can be collected and treated in a centralized mode, rapid assembling and disassembling can be realized, and the operation is facilitated; and the fixing structure is arranged inside the rotating structure for placing the test tube, so that the outer side wall of the inserted test tube can be locked and fixed, the circumstance that the test tube shakes when the reagents are transported is avoided, and liquid leakage is prevented.

Description

technical field [0001] The invention relates to a kit, in particular to a DNA extraction kit, which belongs to the field of kits. Background technique [0002] Deoxyribose nucleic acid (English DeoxyriboNucleic Acid, abbreviated as DNA) is a kind of nucleic acid, one of the four biological macromolecules contained in biological cells. DNA carries the genetic information necessary for the synthesis of RNA and protein, and is an essential biological macromolecule for the development and normal operation of organisms. DNA is a macromolecular polymer composed of deoxynucleotides. Deoxyribonucleotides are composed of bases, deoxyribose sugar and phosphate. There are four bases: adenine (A), guanine (G), thymine (T) and cytosine (C). In the molecular structure of DNA, two polydeoxynucleotide chains coil around a common central axis to form a double helix structure. The deoxyribose-phosphate chains are on the outside of the helix, with the bases facing in. The two polydeoxynuc...

Problems solved by technology

[0003] At present, the general DNA extraction kit has a relatively simple structure, which is basically composed of a box body and a test tube slot for placing test tubes. When the kit needs to be transported, the kit may be tilted. At this time, the test tube placed inside the kit It will be in a tilted state, prone to liquid leakage, and because the inner diameter of the general test tube tank is larger than the outer diameter of the test tube, if there is a bump during transportation, it may cause the test tube to shake violently, seriously affecting the transportation of reagents Safety, and because the general reagents need to be refrigerated, the temperature inside the kit may be high during long-distance transportation, which seriously affects the quality of reagent transportation. If ice packs are placed, the water droplets produced on the ice packs will not It is easy to collect and discharge, and the ice pack is inconvenient to replace and seal for heat preservation. During transportation, it is inconvenient to pull the box body. When it does not need to be moved, the rollers set on the box body are inconvenient to store, and it may be placed unstable. , seriously affect the use of reagents
