Embodiment 1

[0034] Isothermal Amplification Detection of HPV18 Virus

[0035] 1) The specific components of the recombinase-dependent constant temperature amplification reaction reagent are as follows:

[0036]

[0037]2) Prepare two tubes of reagents according to the reaction system in Example 1, and add HPV18 forward primer, reverse primer and fluorescent probe to the system. The two tube systems are respectively numbered as reaction tube No. 1 and reaction tube No. 2 , Then, add 2ulhela cells to No. 1 reaction tube, add 2ul human genomic DNA to No. 2 reaction tube as a negative control, and make up the system to 20ul with sterile water.

[0038] Forward primer (biotin marker): 20pmol

[0039] Reverse primer: 20pmol

[0040] FITC-labeled probe 15pmol

[0041] 3) After mixing, put the No. 1 reaction tube and No. 2 reaction tube into a 37°C constant temperature water bath for reaction, take out the reaction tube after 20 minutes, and denature at 95°C for 10 minutes. Put the two rea...

Abstract

The invention relates to an anti-pollution portable gene detection method and device. The operation procedure comprises the steps that a PCR pipe containing amplification products is put into a device to conduct sealing, and by means of a series of simple manual operations, a detection result visible by eyes is obtained; target nucleic acid amplification products can be detected rapidly, nucleic acid amplification products can be prevented from being polluted, and a false positive result is avoided. Application can be achieved in the aspects of species identification on the gene level in the fields such as pathogen detection on clinical infectious diseases, food pathogenic microbe detection, agriculture, industry, customs and animal husbandry.

Description

technical field [0001] The present invention relates to an anti-pollution portable gene detection method and device, more specifically, to a method for rapidly detecting target nucleic acid sequence amplification in an anti-pollution portable gene detection device using nucleic acid thin film chromatography (test strip) technology. The invention also relates to a kit for rapidly detecting target nucleic acid amplification products using the anti-pollution portable gene detection device and its use in detecting infectious disease pathogens. Background technique [0002] Nucleic acid research has a history of more than 100 years. In the late 1960s and early 1970s, people devoted themselves to the study of gene in vitro isolation technology. In 1983, American scientist Kary Mullis drove on the winding interstate highway and gave birth to PCR. prototype. After two years of hard work, the idea of ​​PCR was confirmed experimentally, and the first PCR patent was applied for in 198...
