Novel coronavirus pneumonia and influenza were the most frequent period of communication in winter and spring. The most important way to control the epidemic is to select new patients with new crown pneumonia from many respiratory patients.

About viral transport medium with swab.

Swabs and virus transport media are a transport and collection system for long-term freezing, transport and collection of clinical specimens containing viruses.

The main species of organisms usually transported through this medium include chlamydia, urea plasma organisms and mycoplasma.

With the outbreak of COVID-19 pandemic, swabs and virus transport mediums were used to freeze and collect SARS-CoV-19 virus samples.

Rub a swab on the skin or vesicles to collect virus samples. The collected samples are then sent to the laboratory with transport media.

Why do swabs need virus transport media？

After virus collection, the traditional method can not be detected by PCR immediately. The virus itself will quickly dissolve in vitro and affect subsequent tests.

What kind of Media do you use to transport specimens?

Since the outbreak of COVID-19, the Virus Transport Medium has played a major role. Sample and nasal swabs are used to protect samples in the sample tube with virus preservation, which improves the accuracy of detection. Virus preservation solution is a solution for virus sampling, preservation and detection. What kinds of virus preservation solution are added to the virus sampling tube?

virus transport medium

There are two types of virus preservation transport Media: inactivated and non inactivated.

The following briefly introduces several principles for the selection of virus preservation solution.

Non inactivated virus transport medium:

The non inactivated type does not contain lysate.

On the basis of Hank’s, BSA (bovine serum albumin) amino acids, vitamins and other nutrients required by the virus are added, which can maintain the activity of the virus in a wide temperature range and maintain the originality of the sample to the greatest extent.

For nucleic acid extraction and detection of the virus, virus culture and separation.

Characteristics of non inactivated preservation solution:

COVID-19 Sample Collection and Transport kits Use process

1. It can maintain virus activity for detection or virus isolation;

2. It has no inhibitory effect on subsequent nucleic acid amplification;

3. stored in cold storage(at 2 ℃ ~ 8 ℃ ).

Inactivation virus transport medium:

Inactivation preservation solution can inactivate the virus in the sample by fully mixing the collected sample with virus lysate and virus nucleic acid preservation solution, and effectively ensure the integrity of virus nucleic acid in the sample.

About the preserved viral RNA samples: used in gene detection, enzyme-linked immunosorbent assay (ELISA), PCR detection and so on.

Inactivation preservation solution includes guanidine salt containing and guanidine salt free.

1. Guanidine salt

(1) Instantly cleaved and inactivated to reduce the risk of sampling;

Sample Universal Viral Transport Medium Kits

Posted on 2021年9月20日2021年12月21日 by Dr. Lee

Sample Universal Viral Transport Medium kits

Cell medical (Dongguan) Co., Ltd. disposable sample universal viral transport medium kits are composed of flocked swabs and test tubes with virus preservation solution (VTM).

The appearance of VTM is clear or red, and there are no precipitates, lumps and other insoluble visible foreign matters.

For collecting, storing and transporting human nasopharyngeal virus samples. Such as COVID-19, mycoplasma, Chlamydia specimens collection, transportation and preservation.

Universal Viral Transport Medium for Viruses

Test principle:

Virus: Composed of a nucleic acid molecule and protein or only protein, and the individual is small and the structure is simple. Because there is no cell structure, the virus cannot replicate itself, but invades its genes into the host cell, using the latter’s replication system to replicate new viruses. After the virus sample is collected, in order to maintain the viability of the virus sample and prolong the survival time of the virus in the sample, the sampling swab will be stored and transported in the transport medium.

Viral transport medium composition and inspection principle:

Viral Transport Medium

1. A combination of multiple antibiotics has broad-spectrum anti-bacterial and anti-fungal effects.

2. As a protein stabilizer, bovine serum albumin (BSA) can form a protective film on the protein shell of the virus, making it difficult to decompose and ensuring the integrity of the virus.

3. The neutral environment constructed by Hank’s buffer helps increase the survival time of the virus and the stability of infection.

4. Phenol red is an acid-base indicator, the discolouration area is 6.6 (yellow)-8.0 (red), and it will be red at 7.2-7.4.

The most stable pH of the outer protein of the virus is 7.2-7.4, which is also the pH range of Hank’s buffer.

If contaminated moulds or bacteria are not inhibited by antibiotics, they will multiply and release carbon dioxide to lower the pH. When the pH value is lower than 7.2-7.4, the stability of the outer protein of the virus will decrease and the decomposition will be accelerated. At this time, the appearance of the sampling solution will change from red to yellow.

What are the main components of Viral Transport Medium(VTM)?

Hank’s solution base, gentamicin, fungal antibiotics, cryoprotectants, biological buffers and amino acids.

On the basis of Hank’s, adding HEPES and other virus stabilizing components can maintain virus activity in a wide temperature range, reduce virus decomposition speed and improve the positive rate of virus isolation.

How to use a universal viral transport medium?

Please read the instructions carefully before use.

Working conditions: room temperature

1. Take out the virus preservation solution.

2. Use a sampling swab for sampling.

3. Insert the swab into the tube containing virus preservation solution, break the tail, leave it in the preservation solution tube, cover the tube cover.
