Problems solved by technology

At present, the commonly used domestic and international detection method for mouse encephalomyocarditis virus (EMV) infection is serological ELISA detection, in which blood collection and serum separation of mice are particularly cumbersome and time-consuming, especially in large-scale experimental animal breeding institutions It is too cumbersome to use the traditional ELISA method for the detection of experimental mice every year, and now there are mouse encephalomyocarditis virus infection detection ELISA kits on the market, most of which are imported kits, and the price is around 2000-3000 yuan. and can only detect 96 times 2 samples
Therefore, the traditional method has the disadvantages of cumbersomeness, limitation, low sensitivity and high price.

Embodiment 1

[0028] Embodiment 1 Fluorescent quantitative RT-PCR detects mouse encephalomyocarditis virus

[0029] 1. Experimental samples

[0030] 120 brain samples from Shanghai Experimental Animal Research Center.

[0031] 2. cDNA synthesis

[0032] Take a small piece of mouse brain tissue, add PBS and steel balls, put it in a shaker for about 1min, centrifuge at 4000rpm for 2min, suck off the supernatant, and extract RNA. The extraction method refers to the instruction manual of the TIANamp Virus RNA Kit extraction box, and the extracted nucleic acid RNA is reverse-transcribed to synthesize cDNA.

[0033] The template is extracted viral RNA, the primer pair is OligdT18, and cDNA is synthesized by reverse transcription. The reverse transcription system (40 μL) is: 20 μL RNA template, 2 μL primer pair, 8 μL 5× reverse transcription buffer, dNTP (10 mmol / L) 4 μL, Ribonuclease Inhibitor (40U / μL) 1 μL, Prime Script reverse transcriptase (200U) 1 μL, DEPC water 4 μL. Water bath at 42°C f...

Abstract

The invention discloses a primer pair, a probe, a kit and a method for fluorescence quantitative PCR detection of murine encephalomyocarditis viruses. The detection method takes cDNA of brain issues of a mouse as a template, SEQ ID No:1 and SEQ ID No:2 as primers and SEQ ID No:3 as the probe to perform fluorescence quantitative RT-PCR amplification and acquire a fluorescence signal. The fluorescence quantitative RT-PCR detection method disclosed by the invention can realize quick, accurate, convenient, rapid and specific detection of murine encephalomyocarditis virus nucleic acids in a mouse body, and the sensitivity, the repeatability and the specificity can be ensured.

Description

technical field [0001] The invention belongs to the technical field of bioengineering, and more specifically, the invention relates to a primer pair, a probe, a kit and a method for detecting mouse encephalomyocarditis virus by fluorescence quantitative RT-PCR. Background technique [0002] Murine encephalomyocarditis virus (EMV) is a member of the genus Cardiovirus in the family Picornaviridae and has only one serotype. Mice are the natural storage host of EMV, and EMV can infect a variety of host animals, including mammals, rodents, arthropods and humans, among which pigs are the most common and severe animal. Mice are extremely susceptible to EMV, and the main manifestations are acute encephalitis, myocarditis, diabetes, orchitis, and conjunctivitis. EMV is a single-strand positive-strand RNA virus with a genome length of about 7.8 kb and a large open reading frame (ORF). Its genome structure is similar to other picornaviruses. The genome homology of the porcine and mou...
