Let you read MTM, UTM, VTM virus preservation solution in one article


As the cumulative number of confirmed cases in China Jilin, Guangdong, Shandong and other places continues to increase, the nationwide nucleic acid detection has become the norm. The virus preservation solution is an important liquid medium added to the nucleic acid detection sampling tube. The commonly used virus preservation Liquids can be divided into VTM, UTM, MTM types. The standard UTM and VTM preservation solutions are designed to transport intact viable microbial or virus samples and culture them, so there are still biological hazards, which will be introduced in detail today. These three types of preservation solutions.
MTM type virus preservation solution
MTM is a molecular transport medium that provides users with a timely "snapshot" of that sample by preserving and stabilizing DNA and RNA. MTM (Molecular Transport Medium) is designed and optimized for molecular detection, allowing safe and efficient collection, transport and processing of pathogenic samples. Including qPCR and next-generation sequencing, it uses a unique patented technology to safely collect samples from patients with highly infectious diseases. It was first launched in 2006 in preparation for a global pandemic and has been used to detect many infectious and high-consequence pathogens, including influenza, RSV, tuberculosis, HIV and coronavirus.
VTM and UTM type virus preservation solution
In some foreign countries, both VTM and UTM refer to virus preservation solution. The full name of UTM is universal transport media, which is literally translated as universal transport medium. In virus sampling tubes, it refers to virus preservation solution. The VTM and UTM here usually refer to non-inactivated preservation solutions. Some manufacturers, VTM is more targeted than UTM, specifically for the preservation and transportation of virus samples.
Although VTM or UTM cannot inactivate the virus, it can also be used for virus surface antigen or antibody detection in addition to nucleic acid detection because it preserves the integrity of the virus. In fact, the inactivated and non-inactivated virus preservation solutions do not say which one is better. Desheng can provide both kinds of preservation solutions according to the requirements of different manufacturers' products and testing environment.
Advantages of MTM type virus preservation solution
1. Another major advantage of MTM is that samples can be safely stored for up to 7 days at ambient temperature or 28 days at 2 to 8°C and can be reused multiple times. In addition to reducing the risk of handling live pathogen samples, this also reduces costs by eliminating cold chain requirements and the need for Category 3 facilities as testing can be performed outside of the container
2. Once the swab or biological fluid is added to the MTM, the user gets a "snapshot" of the inactivated microbial sample in time. The microbial DNA, and more importantly, the labile RNA, is immediately stabilized and preserved at the sampling point. Therefore, samples in MTM do not have to be pre-treated to BLS-III or even BLS-II safety levels, only safe routine laboratory testing practices are required.
These three virus preservation solutions have been introduced, and I believe that everyone's doubts can be answered. Desheng is a professional virus preservation solution manufacturer, and its quality has been recognized by many. Although the epidemic situation in many places is still severe recently, as long as everyone is united and united, I believe that we will soon see the dawn of the dawn, and everything will eventually return to the original beauty and tranquility.
