An nucleic acid integrated detection reagent tube is provided, it includes a main tube and one or more branch tubes, wherein a lysing zone, a cleaning zone and a plurality of separation plugs comprising at least a least a separation plug and a second separation plug which are sequentially disposed, the first separation plug is used for separating the lysing zone and the cleaning zone, a reaction zone is provided in the branch tubes and the second separation plug is positioned at a connection between the branch tubes and the main tube or inside the branch tubes; hydrophobic layers in a liquid or a solid phase disposed at each of the plurality of separation plugs; and a magnetic bead channel for magnetically carrying the nucleic acid to sequentially pass through each hydrophobic layer penetrating to the branch tubes defined in an inner wall of the detection reagent tube.

Nucleic acid integrated detection reagent tube

A nucleic acid integrated detection method and detection reagent tube are provided, separating a lysis solution, a cleaning solution and a reaction solution in a detection reagent tube by providing a plurality of separation plugs in an over-under arrangement and disposing a hydrophobic layer in liquid or solid phase on each separation plug; adding a sample into the lysis solution; extracting nucleic acid in the sample using magnetic nanobeads; and then driving the magnetic nanobeads carrying the nucleic acid to sequentially pass through each hydrophobic layer along a magnetic bead channel and into the cleaning solution and the reaction solution to realize a cleaning and amplification for the nucleic acid, and finally, detecting the nucleic acid of the sample by an external device using an optical detection method, thus realizing a plurality of steps of nucleic acid extraction, cleaning and amplification reactions in the same detection reagent tube.

Nucleic acid integrated detection method and detection reagent tube

The present invention relates to methods of amplification of nucleic acid sequences; more particularly, it relates to methods of amplifying target sequences by utilizing cross priming isothermal amplification. The present invention relates to methods of marking the amplification target sequence during the amplification reaction and rapid detection of the target sequence. The present invention also relates to reagent kits for rapid nucleic acid diagnosis and the nucleic acid detection of pathogenic microorganisms such as bacteria, viruses, as well as to diagnoses related to human genetic diseases.

Cross priming amplification of target nucleic acids

The invention relates to a method for rapid detection of a target nucleic acid amplification product while preventing cross-contamination between target nucleic acid amplification products and avoiding false positives, comprising the steps of: a) leaving the reaction tube unopened after the amplification reaction is finished, so as to prevent the target nucleic acid amplification product from leaking out and resulting in contamination; b) placing the unopened reaction tube inside an enclosed unit, making the target nucleic acid amplification product be transferred to a test strip from the reaction tube in a physically enclosed environment; c) performing detection in a visual read-out manner, and determining the result; d) discarding the enclosed unit in a safety place as a whole without opening it after the detection. The invention also relates to a totally enclosed unit for detecting a target nucleic acid amplification product, and still relates to applications of the totally enclosed rapid detection unit in detection of infectious pathogens, food industry, agriculture, livestock husbandry, customs quarantine control, and determination of DNA.
