Liquid VTM Virus Transport Media And Nucleic Acid Detection

VTM Virus Transport Media and nucleic acid detection,Virus transport media directly supplied by Hubei manufacturer

Many of us know that VTM Virus Transport Media is used in virus detection. Is it used for virus nucleic acid detection or for antibody detection of asymptomatic patients or vaccinated people? Can it be detected without VTM? Maybe some people don't know.

The Virus Transport Media is mainly the component added in the virus sampling tube. Not every sample collection place can be detected by PCR. Therefore, the collected virus swab samples need to be transported. After the samples are sent to the detection institution, they are analyzed by PCR amplification and other methods, which belongs to the nucleic acid detection of virus.

VTM Virus Transport Media for nucleic acid detection

The sampling tube for virus sample collection is composed of sampling tube, sampling swab (nose and throat swab) and Virus Transport Media added in the tube. The preservation solution is divided into inactivated type and non inactivated type:

1. Inactivated preservation solution: it is composed of high concentration of cleavage salt, which can not only quickly destroy the cell membrane of the virus host cell, but also denature the protein to denature and precipitate the virus protein, so that the nucleic acid can get rid of the protein entanglement and release the nucleic acid; It also contains buffer EDTA and Tris and nuclease inhibitors.

2. Non inactivated preservation solution: it consists of Hanks solution, which is mainly made of a variety of inorganic salts, buffers, glucose and 0.4% phenol red under sterilization conditions, which is consistent with the pH value, osmotic pressure and sterile conditions of cell growth state, so as to prolong the survival time of virus host cells in vitro; In addition, it also contains protein protectants to protect virus stability, buffers and cryoprotectors.

Use of Virus Transport Media and sampling tube:

a) Nasal collection: gently insert the swab head into the nasal cavity for sampling, use another swab to collect another nasal sample in the same way, immerse the swab head in the sampling solution and break the tail;

b) Throat collection: collect throat samples with a swab. Similarly, invade the swab head into the sampling solution and break the tail.

Hubei xindesheng Material Technology Co., Ltd. is located in Ezhou, Hubei Province, adjacent to Wuhan. At the most difficult time, Desheng developed virus preservation solution and widely used it to detect covid-19, which has been widely recognized by customers. We seem small in the face of the epidemic, but the power of mankind is infinite. Desheng hopes to give full play to its energy in this battle, And help more people out of this haze.
