Abstract

The invention discloses a reovirus-detecting fluorescence quantitative PCR kit and an application thereof. The kit comprises: a) an RNA extraction solution, b) a reverse transcriptase reaction solution, c) reverse transcriptase, d) an RNA enzyme inhibitor, e) a primer and a TaqMan probe, f) a standard positive DNA template and g) a PCR fluorescence quantitative reaction solution. The kit is characterized in that: primer sequence is a sense primer: 5'-TGCGCCTATCCTTGAGTTGA-3', and an antisense primer: 5'-TTGCCAGGAAATACGGGTCT-3', and the size of an amplicon is 138 bp; the sequence of a fluorescence probe is: 5'-FAM-TCAAAATGGTGGACTTCAGTTTCGATTT-TAMRA-3', the 5' end of the probe is marked with a fluorescence emission group FAM, the 3' end is marked with a fluorescence quenching group TAMRA, the standard positive DNA template transforms a colon bacillus DH5 alpha by a pGEM-T carrier inserted with reovirus S1 protein zone 361 bp segment, plasmid is extracted after proliferation, an A260 ration is measured in an ultraviolet spectrophotometer, and the plasmid is diluted by 10 times of gradient. The kit can efficiently and conveniently monitor the reovirus pollution in serum products in real time, can be applicable to epidemiology investigation of reovirus infection, and can provide technical support for relevant fundamental researches, thus having quite broad application prospect.

Description

Technical field: [0001] The invention relates to the field of biotechnology, more specifically to a fluorescent quantitative PCR kit for detecting reovirus, and also relates to the use of the fluorescent quantitative PCR kit, which is suitable for real-time monitoring of reovirus contamination in serum products At the same time, it is widely used in the epidemiological investigation of the virus infection, and can also provide technical support for related basic research. Background technique [0002] Reovirus belongs to the Reoviridae family (Reoviridae), with a segmented double-stranded RNA genome, no envelope, and a double-layer capsid. It has a wide host range and can infect humans, vertebrates, insects, and plants. 5 genera. It mainly causes diarrhea, dehydration and death in young animals in cattle herds, and is a common disease in dairy and beef cattle herds. The detection rate of antibodies in the herd is extremely high, and the mortality rate is very high during a...
