02 02 This product is used to prepare storage tubes for collecting and transporting various viruses and related samples at room temperature. 1. Inactivated type: Viruses and bacteria lose their infectivity after the effects of receptive factors, called inactivation (inactivation). Most viruses are more likely to be inactivated than bacteria. This also makes long-term preservation of viruses usually more difficult than bacteria. In fact, most viruses are resistant to cold and heat, and are unstable to heat. At 55—60℃, usually within a few minutes, the capsid protein of the virus denatures, causing the virus to lose its infectivity. This may be because the virus has lost its ability to adsorb and/or strip normal cells at this time. Viruses have the disadvantage that they are not easy to store and are susceptible to infection, but inactivated virus preservatives perfectly solve this disadvantage. The virus preservation solution (inactivated type) uses high-concentration guanidine salt to quickly inactivate and preserve respiratory pathogens, so that the sample loses infectivity. The main purpose of it is to lyze the nucleic acid and release the nucleic acid, so that the nucleic acid test is carried out through subsequent real-time fluorescence RT-PCR to determine whether the sample contains viral nucleic acids, that is, infected with the virus. The system contains a high-efficiency virus lytic solution, which inactivates the virus immediately after sampling, effectively preventing the risk of secondary infection. The product can be stored at room temperature for 12 months before sampling, and the sample can be stored at room temperature for one week after sampling. It contains a nucleic acid Rnase inhibitor, which protects the virus nucleic acid from being degraded to a greater extent, and greatly improves the nucleic acid extraction efficiency. 02
