Embodiment 1

[0039] 1. The lyophilized solid-state RT-PCR Mix contains primer sets and probes corresponding to the N gene of SARS-CoV-2, the M gene of influenza A, the M gene of influenza B, and the RNAse P primer sequence of the internal reference gene of human origin. The solid-state RT-PCR Mix mainly contains the N gene of the new coronavirus (SARS-CoV-2), the M gene of the influenza A virus, the M gene of the influenza B virus and the specificity of the genome of the internal standard gene RNaseP before lyophilization. Primers and probes, dNTP, Taq DNA polymerase, reverse transcriptase, RNase inhibitor, UDG enzyme and freeze-dried compound protective agent, and the balance is DEPC treated water. The specific components and contents are shown in Table 2.

Abstract

The invention discloses a multi-fluorescent PCR rapid detection kit for novel coronavirus, influenza A virus and influenza B virus. The kit comprises freeze-dried solid RT-PCR Mix, liquid redissolution Buffer, freeze-dried solid positive control and freeze-dried solid negative control, wherein the freeze-dried solid RT-PCR Mix contains a primer group corresponding to primer sequences of a SARS-CoV-2 specific gene ORF1ab, an influenza A M gene, an influenza B M gene and a human reference gene RNAse P. The kit combines a multi-fluorescent quantitative PCR technology and a freeze-drying process, utilizes three pairs of special primers and human reference genes to amplify specific sequences of three pathogens in vitro, and performs real-time detection in combination with a fluorescent probe. The detection method is simple and convenient to operate, has low requirements for the operation level of detection personnel, and can detect three common respiratory pathogens at a time, the detection time and the detection cost are greatly saved, rapid screening of large-batch samples is realized, the whole detection process only takes 40 minutes to 1 hours, and results are accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of in vitro diagnosis and biological detection, and in particular relates to a fully premixed freeze-dried multiple fluorescent PCR detection kit for novel coronavirus, type A and type B influenza viruses and a detection method thereof. Background technique [0002] Coronavirus disease 2019 (Corona Virus Disease 2019, COVID-19) is an acute respiratory infectious disease caused by a new coronavirus (new Corona Virus, SARS-CoV-2). SARS-CoV-2 belongs to the new type of coronavirus belonging to the genus β. It is an RNA virus with an envelope. The particles are round or oval, often pleomorphic, with a diameter of 60-140nm. It is currently known to infect humans. The seventh coronavirus, the remaining six coronaviruses are HCoV-229E, HCoV-OC43, HCoV-NL63, HCoV-HKU1, SARS-CoV and MERS-CoV. Among them, the first four are more common in the population, with low pathogenicity, and generally only cause mild respirato...
