Embodiment 1

[0104] Example 1 The preparation method of the human papillomavirus (HPV) high-risk type typing detection kit detection mixed solution: 1. Synthesize the oligonucleotide probe according to the following sequence:

[0105]

[0106]

[0107] 2. Preparation of nucleic acid fluorescent PCR detection mixture:

[0108] (1), preparation of HPV16 type and HPV 56 type nucleic acid fluorescent PCR detection mixture:

[0109] Human papillomavirus (HPV) type 16 upstream primer 1.2 μl / test; downstream primer 1.2 μl / test; probe 0.2 μl / test; human papillomavirus (HPV) type 56 upstream primer 1.2 μl / test; downstream primer 1.2 μl / test; probe 0.2μl / test; PCRMIX-20μl / test; deionized water 10.4μl / test and mix well.

[0110] (2), preparation of HPV18 type and HPV 45 type nucleic acid fluorescent PCR detection mixed solution:

[0111] Human papillomavirus (HPV) type 18 upstream primer 1.2 μl / test; downstream primer 1.2 μl / test; probe 0.2 μl / test; human papillomavirus (HPV) type 45 upstream...

Embodiment 2

[0124] Example 2 Use of the Human Papillomavirus (HPV) High-Risk Typing Kit:

[0125] Source of specimens: The specimens used come from clinical medical units.

[0126] 2.1 Processing of test specimens:

[0127] Add 1ml of sterile saline to the specimen, shake well, absorb the liquid and transfer it to a 1.5ml centrifuge tube, and centrifuge at 13,000rpm for 5 minutes. Add 1 ml of sterile saline to the precipitate, mix well, centrifuge at 13,000 rpm for 5 minutes, and repeat the washing once. The precipitate was directly added to 50 μl of nucleic acid extraction solution and mixed thoroughly, bathed in boiling water for 10 minutes, then centrifuged at 13,000 rpm for 5 minutes, and 4 μl of the supernatant was taken as a PCR reaction template.

[0128] 2.2 Reagent preparation:

[0129] (1) Take 36 μl HPV16 and HPV56 nucleic acid fluorescent PCR detection mixture and 0.4 μl Taq enzyme, shake and mix for a few seconds, and centrifuge at 3000 rpm for a few seconds.

[0130] (2)...

Embodiment 3

[0154] Example 3 Human papillomavirus (HPV) high-risk type typing detection kit clinical sensitivity and specificity test:

[0155] 3.1 Specimen: 50 specimens that have been clinically classified into HPV high-risk types

[0156] 3.2 Sample processing, reagent configuration, sample loading and PCR amplification are the same as Example 1

[0157] 3.3 Test results:

[0158] Among the 50 specimens, the test results of the high-risk HPV typing test kit and the clinical unit were both positive in 42 cases, and the sensitivity of the high-risk HPV typing test kit was 97.67% ; Human papillomavirus (HPV) high-risk type detection kit detection results and clinical unit detection results were negative in 7 cases, and the specificity of human papillomavirus (HPV) high-risk type detection kit was 100%; The accuracy of the HPV high-risk typing detection kit is 98%. The specific test results are shown in the table below.

Abstract

The invention relates to a kit for auxiliary diagnosis of cervical carcinoma and high-grade cervical intraepithelial lesion, and discloses a kit for detecting high-risk HPV. The kit for detecting the high-risk HPV comprises a high-risk HPV nucleic acid fluorescent PCR detection mixture and Taq enzyme. The invention also discloses a method for preparing the kit for detecting the high-risk HPV and a method for using the same. The kit can be used for detecting the high-risk HPV and overcomes the defects of high false positive rate, low specificity, high cost and the like of typing detection of the high-risk HPV in the prior art.

Description

technical field [0001] The invention relates to a diagnostic reagent for human papillomavirus (HPV), in particular to a kit for detecting high-risk human papillomavirus and its preparation and application. Background technique [0002] HPV is the English abbreviation of human papillomavirus, which is a general term for a group of viruses, forming a family, and their virus shapes are similar. At present, there are more than 80 HPV types that have been identified. According to the risk of different types of HPV and tumor occurrence, they are divided into low-risk types and high-risk HPV types. High-risk HPV types include HPV16, 18, 31, and 33. , 35, 39, 45, 51, 52, 56, 58, 59, 68, a total of 13 types, which are related to the occurrence of cervical cancer and cervical intraepithelial high-grade lesions. A large number of studies on the etiology of cervical cancer have confirmed that high-risk HPV infection is a necessary factor for the occurrence of cervical cancer. The pers...
