What is the lysed salt in the virus transport media?
Latest company news about What is the lysed salt in the virus transport media?

Virus transport media is a kind of liquid to protect the tested substance of virus by immersing the virus sample on the sampling swab in the sampling tube. It is generally divided into two types: one is activated type, which can protect the protein and nucleic acid of virus; the other is inactivated type, which usually contains the lysate of inactivated virus, which can lyse the protein and protect the nucleic acid.

 

Therefore, the virus transport media added with lysed salt is an inactivated virus transport media. The main purpose of the contained Tris, lysed salt, EDTA, etc. is to lyse the nucleic acid and release the nucleic acid, so as to carry out by subsequent real-time fluorescent RT-PCR Nucleic acid detection, to determine whether the sample contains viral characteristic nucleic acid, that is, whether it is infected with a virus.

Inactivated and activated virus transport media

 

Nucleic acid is a biological macromolecular compound composed of many nucleotides, including deoxyribonucleic acid (DNA) and ribonucleic acid (RNA). It is one of the most basic substances in life. The virus has a single structure and contains only one kind of nucleic acid and protein, so when the characteristic nucleic acid is detected, the virus is detected. Viruses are parasitic organisms and cannot survive in vitro after sampling. If they cannot be detected in time, they need to be put into the virus transport media. In order to protect the security of the virus detection environment, it is necessary to add a lysed salt to inactivate the virus and release the nucleic acid that can be detected.

 

Guanidine is a nitrogen-containing organic compound, also known as "iminourea", "imicarbazide", and "carbamidine". Cleavage salts are strong inhibitors of nucleases and facilitate the extraction of complete RNA from RNASE-rich tissues. The lysed salt can not only quickly destroy the cell membrane, but also denature the protein, so that the protein is denatured and precipitated, so that the nucleic acid can get rid of the protein. The inactivated virus transport media containing lysed salt can fully and effectively lyse the cell, so that the nucleic acid in the cell can be fully released, and a higher concentration of nucleic acid is obtained, which is conducive to improving the quality of the nucleic acid and ensuring the accuracy of subsequent operations.

 

In addition to the inactivated virus transport media, Desheng developed and produced a activated virus transport media, which not only saves the integrity of the virus, but also has a higher detection rate. It can also be used for other research besides nucleic acid detection. The inactivated virus transport media is safer to use, the operating environment requirements are not so strict, and each has its own advantages.
