What are the advantages of Desheng's inactivated virus preservation solution?

Currently there are inactivated and non-inactivated virus preservation solutions on the market. Since almost all non-inactivated virus preservation solutions directly store live viruses, medical staff during sampling, transportation and testing may face a higher risk of infection. In this case, the anti-epidemic front line needs a sample preservation solution that can directly inactivate the virus, which can greatly improve the safety of sample collection and transportation. However, it should be noted that while inactivating the virus, the preservation solution should also consider whether the integrity of the viral nucleic acid can be stably preserved, so as to avoid degradation of the nucleic acid in the sample before detection, resulting in "false negative" nucleic acid detection.

Because the current nucleic acid detection is to detect the viral RNA in the sample, the virus needs to be lysed, so it is enough to ensure the integrity and stability of the viral nucleic acid, and there is no need to save the live virus. Therefore, in the current situation of fighting against the new coronavirus epidemic, it is more ideal to inactivate the virus while collecting samples. But how do we make sure that the virus will not be degraded before the sample is tested, resulting in "false negatives" in the test?

The virus sample preservation solution independently developed by Desheng contains special bovine serum albumin and Hanks buffer. Bovine serum albumin (BSA) as a protein stabilizer can form a protective film on the protein shell of the virus, making it difficult to decompose , The virus is inactivated, and the protein shell forms a protective film to make it difficult to decompose and ensure the integrity of the virus; the neutral environment constructed by Hanks buffer helps increase the survival time and infection stability of the virus. The preservation effect of viral nucleic acid is significantly better than that of other manufacturers' conventional lysis solutions, which is very conducive to the preservation of samples for current new coronavirus nucleic acid detection.
