A dna extraction kit

Abstract

The invention relates to the field of kits, specifically a DNA extraction kit, comprising a box body, a rotating structure, a fixed structure, a clamping structure, a freezing structure, a pulling structure and a moving structure; The structure can not only play a role of sealing protection for the box body, but also ensure that the test tubes placed inside the box body are always in a vertical state, so as to avoid the leakage of the test tube when the box body is transported, which greatly increases the reagent consumption. Excellent transportation safety, and with the freezing structure installed inside the box, it can not only refrigerate the reagents placed inside the box, but also collect and process the condensed water droplets outside, and can also achieve rapid installation And disassembly, easy to operate, by setting a fixed structure inside the rotating structure where the test tube is placed, the outer side wall of the inserted test tube can be locked and fixed, avoiding the shaking of the test tube when transporting reagents, and preventing liquid leakage.

Description

A DNA extraction kit technical field The present invention relates to the field of test kits, specifically a DNA extraction kit. Background technique Deoxyribonucleic acid (English DeoxyriboNucleic Acid, abbreviated as DNA) is the four A kind of nucleic acid, one of biological macromolecules. DNA carries the genetic information necessary for the synthesis of RNA and proteins, and is the Biomacromolecules essential for development and normal functioning. DNA is a macromolecular polymer composed of deoxynucleotides. deoxynucleosides Acids are made up of bases, deoxyribose and phosphoric acid. There are 4 bases: adenine (A), guanine (G), thymine (T) and cytosine Pyrimidine (C). In the molecular structure of DNA, two polydeoxynucleotide chains are coiled around a common central axis, forming a double helix structure. The deoxyribose-phosphate chain is on the outside of the helix, with the bases facing inside. Two polydeoxynucleotide chains are reverse complement...

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
