How to choose professional virus transfer media

What’s the usage of a virus transfer media?we can tell that its product use is for the collection, transportation and storage of samples.Virus preservation solution is a protective liquid medium added in the virus transfer media to protect the samples after nasopharyngeal swab sampling. It is usually called virus preservation solution in China, and it is often referred to as VTM solution or UTM solution for short. Usually, in nucleic acid detection, nucleic acid PCR can’t be carried out directly at the sample collection place, and VTM needs to be added when the samples collected by swabs need to be transferred for detection.

Product features of a virus transfer media: 1. Bovine serum albumin was added into the upgraded HANK solution, which provided nutrition for the virus and kept its vitality and toxicity. 2. Antibiotics are added into the preservation solution, which improves the bacteriostatic effect of the sample solution stored at normal temperature on bacteria and solves the pollution problem of bacteria and fungi after sampling. 3. Buffer salt and phenol red for controlling pH value are used as pH indicator. 4. Adding antifreeze does not affect the normal use in low temperature environment, which is beneficial to the preservation of virus when the specimen is frozen.

Usage of Medico disposable virus transfer media:

According to sampling requirements, collect samples with sampling swab. After collecting the sample into the sampling tube, place the sampling swab. Break the swab at the breakable cutting point of the sampling swab rod, and discard the tail.  Tighten the sampling tube cover. Mark the information on the sample tube label as required. After the specimen is collected, it should be transported to an inspection laboratory with inspection ability within 3 working days. The storage temperature is 2-8 DEG C; If it is not sent to the laboratory within 72 hours, it should be kept at -70℃ or below, and the specimen should avoid repeated freezing and thawing.
