The new crown virus has broken the otherwise peaceful life and messed up people's lives. It is because of the extremely high risk of infection that everyone is afraid and cautious. When difficulties arise, methods to solve them will follow. In order to determine whether they are infected with the new crown virus, nucleic acid testing has made its debut. Nucleic acid testing is an important means to confirm the new coronavirus, and it is also one of the important processes for patients to confirm the diagnosis. To do nucleic acid testing, Nucleic acid detection has the characteristics of early diagnosis, high sensitivity and specificity, and is the "gold standard" for diagnosing new coronary pneumonia. Currently, the most widely used real-time fluorescent quantitative RT-PCR technology. Generally, the two targets located on the ORF1ab and N genes of the virus are detected. The same specimen must meet the double target positive or the repeated test as single target positive, or the two specimens must meet the single target at the same time to confirm the positive of SARS-CoV-2 virus nucleic acid. The virus transport medium developed by Desheng for the new coronavirus is inactivated and non-inactivated. The nucleic acid detection mainly uses an inactivated virus transport medium, which can instantly crack the pathogen and release the nucleic acid, and the protective agent can prevent the nucleic acid from being degraded. . By fully mixing the collected sample with the virus lysis solution and the virus nucleic acid preservation solution, the virus in the sample can be inactivated. Colleagues can effectively ensure the integrity of the virus nucleic acid in the sample. The collected sample can be transported and processed under normal temperature conditions. Long-term preservation. The saved viral RNA samples can be widely used in genetic testing, enzyme-linked immunoassay (ELISA), PCR testing, etc. Although Desheng does not currently have the technology to produce nucleic acid detection kits, it can produce virus preservation solutions, disposable virus sampling tubes and biological buffers required for nucleic acid detection, as well as luminol and acridine as the raw materials for antigen and antibody detection. ester. Desheng is willing to contribute its part in the fight against the epidemic, and is willing to fight for the cause of human health.

The chemical name of the biological buffer HEPES product is: 4-hydroxyethylpiperazine ethanesulfonic acid, a white crystalline powder. It is a weak acid and a zwitterionic buffer in organic chemicals. The decomposition ability of the substance can increase with the increase of temperature, and decrease with the decrease of temperature. However, compared with other buffers, its decomposition constant does not change much with temperature. This makes HEPES buffers more effective at low temperatures. A buffer to keep the structure and function of the enzyme well. It is widely used in many fields such as clinical laboratory diagnostic reagents, life science research, pharmacy and biotechnology. 1) The research of biological buffer HEPES on promoting the stability of foot-and-mouth disease antigen. Foot-and-mouth disease antigen is easily degraded during storage and vaccine preparation, which affects the vaccine effect. The degradation rate of the foot-and-mouth disease antigen is related to the stability of the pH value of the maintenance solution. The preparation of a maintenance solution with strong pH stability can improve the quality of the foot-and-mouth disease vaccine. 2) Preparation of a skin care product containing a biological buffer, which contains a microbial fermentation product extract, which is characterized in that it also contains a biological buffer with a mass percentage of 0.1%-3.0%.

Since the outbreak of the epidemic, relevant diagnostic reagent R&D and production companies have introduced RT-PCR nucleic acid detection kits for the first time. By collecting oropharyngeal swab or nasopharyngeal swab samples, the RNA of the virus is extracted and purified for qualitative or quantitative detection. "2019 -New Coronavirus". The sample collection and storage container used in this method is a "disposable virus sampling tube". The new coronavirus nucleic acid detection, disposable virus sampling tube can be said to be indispensable. Next, Desheng intends to introduce the composition and use of the virus sampling tube. About the composition and manufacturing of the virus sampling tube: 1. Sampling swab: The sampling swab directly contacts the sampling site, and the material of the sampling head is closely related to the subsequent detection. 2. Virus preservation solution: There are two main types of virus preservation solution widely used in the market. One is the improved virus maintenance solution based on the delivery medium, and the other is the improved preservation solution of nucleic acid extraction lysis solution. 3. Preservation tube: The material of the preservation tube should be selected carefully. There are data indicating that Polypropylene is related to the adsorption of nucleic acids, especially when the ion concentration of high tension is high, polyethylene plastic (Polyethylene) is better than polypropylene (Polypropylene). Easy to grasp DNA/RNA. About the use of virus sampling tube: The virus sampling tube sampling is mainly divided into oropharyngeal sampling and nasopharyngeal sampling: 1. Oropharyngeal sampling: first press the tongue with a tongue depressor, and then put the sampling swab head into the throat to wipe the bilateral pharyngeal tonsils and back wall of the pharynx, wipe the back wall of the pharynx with light force, avoid touching the tongue unit. 2. Nasopharyngeal sampling: use a swab to measure the distance from the tip of the nose to the earlobe and mark it with your fingers. Insert the sampling swab into the nasal cavity in the direction perpendicular to the nose (face). The distance of the swab should be at least half the length of the earlobe to the tip of the nose. Leave the swab in the nose for 15-30 seconds, gently rotate it 3-5 times, and withdraw the swab. It is not difficult to see from the method of use that whether it is an oropharyngeal swab or a nasopharyngeal swab, sampling is a technical task, which is difficult and easy to contaminate. The quality of the collected sample is directly related to the subsequent testing. If the viral load of the collected sample is Low, easy to cause false negatives, difficult to diagnose.

Name Testing kit for New coronavirus (2019-nCOV) IgG/IgM antibody Rapid Test WB/S/P Specifications 25 tests Introduce This kit uses the colloidal gold immunochromatographic principle to qualitatively detect novel coronavirus igg/igm antibodies in human serum, plasma, or whole blood. the sample to be tested was added to the sample hole of the test paper, and then added 2 drops of sample diluent. the igg/igm antibody in the sample combined with the recombinant new coronavirus antigen labeled with the colloidal gold on the binding pad formed complex. under the action of chromatography, it diffused forward along the nitrocellulose membrane (nc membrane). the nitrocellulose membrane was fixed with two detection lines (g line, m line) and one quality control line (c line). the g line was fixed with anti-human igg antibody for the detection of new coronavirus igg antibody; the m line was fixed with anti-human igm antibody for the detection of new coronavirus igm antibody; and the c line had quality control for the detection of the new coronavirus ig antibody. If the sample contains a new coronavirus IgG antibody, then the antibody binds to the recombinant new coronavirus antigen labeled with colloidal gold, diffuses forward, and then binds to the anti-human IgG antibody fixed on the NC membrane detection line (G line). if the sample contains a novel coronavirus igm antibody, then the antibody binds to the recombinant new coronavirus antigen labeled with colloidal gold, diffuses forward, and then binds to the anti-human igm antibody fixed on the nc membrane detection line (m line). The darker the color of the colloidal gold accumulated on the detection line, the higher the concentration of the new coronavirus antibody in the sample. To monitor the effectiveness of the test card, set up a quality control line (line C), whether there is a detection line (line T), quality control line (line C) should be color, otherwise the test results are judged invalid.
