Problems solved by technology

However, these two detection systems are mainly established for the subtype B virus strains prevalent in Europe and the United States. Antimicrobial resistance detection of serotypes and other popular recombinant virus strains is not ideal
In addition, these two commercial drug resistance detection kits are expensive, which is not conducive to large-scale clinical application in my country
However, the in-house methods built by some domestic research institutions have played a certain role in the detection of HIV drug resistance in China, but these in-house methods are cumbersome to operate, and more importantly, the operation process and analysis methods are not uniform, making it difficult to truly detect HIV drug resistance. Effective for large-scale clinical testing

Embodiment 1

[0088] Amplification and sequencing primers of the Pol gene region of embodiment 1, HIV-1

[0089] The present invention downloads the full-length genome sequence of HIV-1 virus worldwide from the HIV database (http: / / www.hiv.lanl.gov / ), and utilizes appropriate evolutionary analysis software to analyze the global, Asian and Chinese The evolutionary analysis of the full-length genome sequence of the HIV-1 virus in China was carried out, and the evolutionary relationship and trend of different subtypes of HIV-1 viruses were obtained. According to the evolutionary relationship, the full-length genome sequences of 13 subtypes, including B, B' (Thailand B), CRF-01AE, CRF-07BC, and CRF-08BC, with high prevalence and wide geographical coverage were selected, and the appropriate nucleic acid homology analysis was used The software carries out conservation analysis to the Pol gene region of HIV-1, finds out the highly conserved section of the candidate (conservation is greater than 98...

Embodiment 2

[0102] Embodiment 2, HIV-1 genotype drug resistance detection kit and detection method thereof

[0103] The kit of the present invention comprises RT-PCR amplification reagent A, RT-PCR amplification reagent B containing primer 1 and primer 2 in Example 1, RT-PCR amplification reagent C, and primer 3 in Example 1 PCR amplification reagent D with primer 8, sequencing amplification reagent 1-6 containing primer 3-primer 8 in Example 1. The detection method of the kit is as follows:

[0104] 1. Extraction of RNA

[0105] Extract the RNA in HIV-1 from the serum or plasma of the HIV-1 patient to be tested (from the AIDS Research Institute of the First Affiliated Hospital of China Medical University, informed by the patient, clinically diagnosed, containing drug resistance sites I84V, A71V and K101E) ,Specific steps are as follows:

[0106] 1. Add 20 μL proteinase K to a clean 1.5mL centrifuge tube;

[0107] 2. Add 200 μL of patient plasma sample to the centrifuge tube;

[0108...

Embodiment 3

[0186] Embodiment 3, the application of the detection kit of HIV-1 genotype drug resistance

[0187] Plasma samples of 50 HIV-1 infected persons with known genotypes and drug-resistant loci were collected (the First Affiliated Hospital of China Medical University, patients were informed and clinically diagnosed, and the genotypes and drug-resistant loci of 50 clinical samples were collected. Detecting result is shown in table 9), with the detection kit of HIV-1 genotype drug resistance and detection method thereof among the embodiment 2 to the genotype of 50 routine HIV-1 infected persons plasma samples and drug-resistant locus detection.

[0188] The genotype drug resistance detection results of 50 cases of clinical samples are as shown in Table 9: in 50 cases of clinical samples, the proportion of samples with drug resistance sites in the protease gene region was 22% (11 / 50); there was drug resistance in the reverse transcriptase gene region The sample ratio of the site is ...

Abstract

The invention discloses an HIV-1 genotype and drug resistant mutation site detection kit and application thereof. The kit comprises set of primers detecting to-be-detected HIV-1 genome's genotype and drug resistant mutation site. The set of primers include amplification primer pairs and sequencing primer sets. Experiments prove that the detection kit provided by the invention ensures the detection capability of low-frequency mutant strains, greatly makes up the disadvantages of poor amplification efficiency, low detection rate and low low-frequency mutation detection rate of similar kits imported from abroad to China HIV epidemic strains, has the characteristics of simple and fast operation, high efficiency, economical efficiency and high throughput, etc., not only lays a solid foundation for domestic production of HIV drug resistant detection reagents, but also opens up broad prospect for domestic large-scale detection of HIV virus strain drug resistant situation.

Description

technical field [0001] The invention relates to a detection kit for HIV-1 genotype and drug resistance mutation site and application thereof, belonging to the field of biotechnology. Background technique [0002] Since 1981 when the United States first discovered that AIDS (AIDS) was caused by human immunodeficiency virus (HIV) infection, AIDS has spread rapidly around the world. According to the report on the global AIDS epidemic jointly released by UNAIDS and the World Health Organization, as of 2009, the total number of infected people in the world was 33.4 million, the number of newly infected people was about 2.7 million, and the death toll was 2 million. , 2.1 million infected people under the age of 15, with more than 7,400 new infections every day worldwide. However, the number of HIV infections in my country is increasing at a rate of 3% every year, and the trend of epidemic development is severe. According to the estimated report on the AIDS epidemic in China rel...
