In the new crown test, whether it is nucleic acid or antigen, the nasopharyngeal swab after sampling needs to be put into a preservation tube with a preservation solution, so it is also a preservation solution. Is virus transport media and antigen transport media the same thing Can it be shared
Nucleic acid amplification testing
The target of the new coronavirus nucleic acid detection is the nucleic acid gene fragment inside the virus. Virus transport media is to protect viral nucleic acid from rapid degradation in vitro, so as to facilitate nucleic acid sequence amplification for detection purposes. The main components are balanced salts, chelating agents, guanidine salts, surfactants, etc.
Antigen detection
The target of the new coronavirus antigen test is the specific protein on the surface of the virus. The main components of the antigen preservation solution are low ionic strength buffers (such as Tris buffer, PBS buffer, etc.) and surfactants (such as Brij58, Triton X-100, etc.).

virus transport media and antigen transport media
The main function of antigen transport media is to protect the antigen protein from protein denaturation or decomposition, and it can react with the gold-labeled specific antibody on the detection strip. The guanidine salt and other components in the nucleic acid preservation solution will denature the antigen protein, affect the antigen-antibody reaction, and cannot form the antigen-antibody complex, resulting in false negative or invalid results. Therefore, the preservation solution of new coronavirus nucleic acid and antigen cannot be shared.
Preservation solutions from different manufacturers cannot be mixed
To sum up, virus transport media and antigen transport media are not the same thing. In addition, the antigen preservation solutions of different manufacturers cannot be mixed, and the components of different brands of products are quite different, and the performance (specificity and sensitivity) of the antigen detection reagents of each manufacturer is related to the pH value of the supporting preservation solution. The specificity and sensitivity of the reagents are optimal when the optimum pH for the antigen-antibody reaction of most chromatography methods is alkaline. When using a non-matching sample preservation solution, the pH value of the reaction environment will change, resulting in false positive or false negative results.
Desheng currently produces inactivated and non-inactivated virus transport media, with a daily shipment of tens of tons. Generally, customers who cooperate with us have long-term and stable repurchase, which fully shows that the quality is recognized by the public. , regardless of whether the customer's demand is large or small, Desheng will arrange production and delivery as soon as possible, even if it is dozens of tons, it will be a night battle to ensure that customers receive it as soon as possible. If you need virus preservation solution or other blood collection tube reagents, please contact Desheng Company and we will serve you wholeheartedly.
