Embodiment 1

[0038] Test each blood sample according to the following method:

[0039] 1. Process serum samples according to the product instructions to extract viral nucleic acid.

[0040] 2. Add PCR amplification solution, amplify and label the processed nucleic acid sample, and use BIOTIN-labeled primers to label the product with biotin.

[0041] 3. Add 10-20ul to the reaction area.

[0042] 4. 42°C heat preservation and moisturizing reaction for 60 minutes.

[0043] 5. Wash 4-6 times with lotion, 2 minutes each time, shake.

[0044] 6. Add affinity reaction solution, 10-20ul.

[0045] 7. React at 42°C for 15-20min.

[0046] 8. Wash 4-6 times with lotion, 2 minutes each time, shake.

[0047] 9. Add detection solution 20ul / well, so that the detection solution is evenly distributed in the reaction area.

[0048] 10. CCD detection, exposure for 30-60 seconds depending on the strength of the luminescent signal.

Embodiment 2

[0050] Test each blood sample according to the following method:

[0051] 1. Process serum samples according to the product instructions to extract viral nucleic acid.

[0052] 2. Add PCR amplification solution, amplify and label the processed nucleic acid sample, and use fluorescently labeled primers to label the product with fluorescence.

[0053] 3. Add 10-20ul to the reaction area.

[0054] 4. 42°C heat preservation and moisturizing reaction for 60 minutes.

[0055] 5. Wash 4-6 times with lotion, 2 minutes each time, shake.

[0056] 6. Use a confocal fluorescence microscope or a fluorescence scanner to detect and obtain the results.

[0057] Result judgment:

[0058] According to the CutOff value of different indicators, refer to the gradient curve of the standard to determine the negative or positive of the sample serum.

[0059] At the same time, the serum samples tested were routinely tested by conventional methods. The result shows that the test result obtained b...

Abstract

The invention provides a hepatitis B virus e antigen immune evasion detection gene chip and a kit, belonging to the gene chip technique field of clinical detection, and comprising: a gene chip of a specific DNA probe which detects hepatitis B virus e antigen immune evasion and is fixed on a solid phase carrier as well as a matched reagent; the matched reagent includes a treating fluid for treating serum samples, an amplifying solution for amplifying and labeling the treated samples, a hybridization solution in hybridization reaction with a micro-array, a cleaning solution, an enzyme-labeled working solution and a detection liquid; and the matched reagent and the hepatitis B virus e antigen immune evasion detection gene chip are used jointly in the detection process of the serum samples. The chip and the kit can detect the hepatitis B virus e antigen immune evasion, and avoid the clinical hepatitis B virus e antigen leak detection, thereby being favorable for judging the infectivity and conditions after curing of hepatitis B patients.

Description

technical field [0001] The invention belongs to the technical field of gene chips for clinical detection, and in particular relates to a gene chip for detecting hepatitis B e antigen immune evasion and a kit thereof. Background technique [0002] my country is the country with the most severe HBV infection in the world. Usually, two-and-a-half detection of hepatitis B is an important part of clinical diagnosis and blood screening. Hepatitis B e antigen is an important indicator in the detection. The e antigen is derived from the core of the hepatitis B virus. The detection of e-antigen is equivalent to the detection of the core antigen, which means that the virus is actively replicating and highly contagious. To know whether HBsAg-positive people are contagious, the more commonly used and reliable detection method is to test e-antigen and e-antibody. Hepatitis B e antigen immune evasion can lead to missed detection of hepatitis B e antigen in clinical serology, which is ...
