Embodiment 1

[0034] The establishment of embodiment 1 fox retrovirus SYBR Green Ⅰ fluorescent RT-PCR detection method

[0035] 1. Primer design and synthesis

[0036] According to the POL gene sequence of fox retrovirus measured in the previous research of our laboratory, after sequence comparison, the conserved region was selected to design amplification primers. There were 3 pairs of primers, and the sequences were as follows:

[0037] First pair of primers:

[0038] SEQ ID No.1: Upstream primer ACCTGGGACTACGACACTG,

[0039] SEQ ID No.2: downstream primer CCTGCTGGCGTCTCATCT;

[0040] Second pair of primers:

[0041]SEQ ID No.5: Upstream primer CGGGTGGTCCCGACCTG,

[0042] SEQ ID No.6: downstream primer GTTCCATCTTTCCCCTGC;

[0043] The third pair of primers:

[0044] SEQ ID No.7: Upstream primer CAAAGGTACGTGCTATAGTG,

[0045] SEQ ID No.8: downstream primer CTCTAACTTATTACAAATAC;

[0046] The above primer sets were synthesized by General Biosystems (Anhui) Co., Ltd.

Embodiment 2

[0071] Embodiment 2 kit sensitivity analysis

[0072] The test kit provided in Example 1 was used for testing.

[0073] (1) Prepare the pMD-POL standard solution, calculate the copy number according to the concentration of the pMD-POL plasmid standard product respectively, and the pMD-POL plasmid copy number is 3.2×10 10 copy / μL;

[0074] Dilute the plasmid standard in a 10-fold ratio serial gradient, and take 10 6 Copy / μL~10 -1 Copy / μL pMD-POL plasmid standard product is used as the plasmid standard product template, and the obtained template solutions are numbered respectively, as follows:

[0075] Standard template 1: 3.2×10 6 pMD-POL plasmid standard in copies / μL;

[0076] Standard template 2: 3.2×10 5 pMD-POL plasmid standard in copies / μL;

[0077] Standard template 3: 3.2×10 4 pMD-POL plasmid standard in copies / μL;

[0078] Standard template 4: 3.2×10 3 pMD-POL plasmid standard in copies / μL;

[0079] Standard product template 5: 3.2×10 2 pMD-POL plasmid stand...

Embodiment 3

[0088] Embodiment 3 kit specificity analysis

[0089](1) Prepare the template: use plasmid pMD-POL, canine distemper virus, fox parvovirus, infectious hepatitis virus, Escherichia coli, Pasteurella, and Staphylococcus genome as templates, and nuclease-free water as a control, and set aside;

[0090] (2) Fluorescent RT-PCR amplification: The total system of fluorescent RT-PCR is 20 μL: 10 μL of 2×Onestep TB Green RT-PCRBufferⅢ, 1 μL of enzyme mixture, 2 μL of primer set, 6 μL of nuclease-free water, add to 0.1 mL amplification tube , prepare 8 parts, stand-by; marked as 1#, 2#, 3#, 4#, 5#, 6#, 7#, 8# for use;

[0091] Add the plasmid pMD-POL, canine distemper virus, fox parvovirus, infectious hepatitis virus, E. In #, 6#, and 7#, add nuclease-free water to 8#, after adding the sample, centrifuge briefly, and put it in a fluorescent PCR instrument for amplification reaction;

[0092] Fluorescent RT-PCR amplification conditions were: reverse transcription at 42°C for 5 min; pre...

Abstract

The invention provides a fox retrovirus SYBR Green I fluorescent RT-PCR kit and a use method. The kit comprises a nucleic acid releasing agent, 2 * One step TB Green RT-PCR Buffer III, an enzyme mixed solution, a negative control, a positive control and a primer group; the nucleotide sequence of the primer group is a specific base sequence as shown in SEQ ID No. 1 and SEQ ID No. 2; and the use method comprises the following steps: preparing a to-be-detected sample template, performing fluorescent RT-PCR amplification and analyzing a result. The detection primer is used in the SYBR Green I fluorescent RT-PCR kit, so that the kit has the advantages of wide applicability and strong applicability, and also has the advantages of high detection accuracy and strong specificity; and in addition, by using the kit, fox retrovirus detection can be completed through one-time sample adding, the detection process is simple, and operation is easy.

Description

technical field [0001] The invention relates to the technical field of biological detection, in particular to a fox retrovirus SYBR Green I fluorescent RT-PCR kit and a use method. Background technique [0002] Fox retroviruses can cause serious diseases in foxes. The clinical manifestations are slow growth, increased feed-to-meat ratio, severe immunosuppression, and decreased resistance in foxes, which are prone to secondary diseases and lead to high mortality. This disease is a new disease that seriously affects the economic benefits of the fox breeding industry in recent years, and has caused serious economic losses to the fox breeding industry. [0003] Early and rapid detection of the virus is the key to the prevention and control of the disease. However, in the current literature, there are very few records and reports about the retrovirus. Virus isolation and culture operations are cumbersome and difficult to isolate successfully. In order to monitor the clinical o...
