| Message: | There are two kinds of virus preservation solutions developed by Desheng since the outbreak, which are inactivated and non inactivated. This can better guarantee your choice in the test. But whatever it is, the first thing we need to know is the advantages of the virus preservation solution itself and whether it meets the standards you need.
Non inactivated type
Non inactivated virus preservation solution contains Hanks solution base, gentamicin, fungal antibiotics, BSA (V), cryoprotectant, biological buffer and amino acids.
Combined with many antibiotics, it has antibacterial and antifungal effects;
As a protein stabilizer, bovine serum albumin (BSA) can form a protective membrane on the protein shell of the virus, which makes it difficult to decompose and ensure the integrity of the virus;
The neutral environment constructed by Hanks buffer helps to increase the survival time and infection stability of the virus.
Inactivated type
Inactivated preservation solution can reduce secondary infection and realize safe transportation.
It contains high efficiency enzyme inactivation reagent, which can quickly inactivate various enzymes including DNA and RNA, remove the hidden danger of nucleic acid degradation and eliminate false negative.
It contains special nucleic acid protectant and stabilizer, which can make the released virus DNA / RNA no obvious degradation in 4 days at room temperature, so as to buy time for collection and transportation.
The preserved samples can be directly used for subsequent nucleic acid purification without affecting the detection results.
No matter what kind of solution is stored at low temperature, we should ensure that no matter what kind of solution is stored at low temperature, we should ensure that there is no error. It is very important to maintain the stability of the virus because of its rapid propagation. |
