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.

4. Store it at 2-4 ℃ and use it within 48 hours.

What is saliva collection kit?

In recent years, with the development of medicine, the examination technology has become more and more high-end. And the examination items have become more and more accurate.

Saliva is a complex mixture, which not only contains various proteins. It also contains DNA, RNA, fatty acids and various microorganisms. Therefore, it is possible to diagnose diseases by detecting saliva. Gene detection and analysis.

Saliva collector plays an important role in the process of collecting, transporting and storing saliva samples.

It is noninvasive and easy to self-management, and reduces the risk of medical staff exposure.

Saliva Collection Kit suitable for SARS-CoV-2 sample collection.

Nucleic acid detection is the most widely used new crown detection method.

Including PCR nasopharynx swab, oropharyngeal swab and saliva sample test.

High precision. As long as the collection, breeding and separation of nucleic acids are successful, there is basically no false positive or false negative.

But the sampling staff are easy to be exposed and the risk is high; With one more step of extracting nucleic acid, unskilled technicians are likely to fail to extract, resulting in false negative, or pollute with other people's samples, resulting in false positive.

COVID-19 Pooled Sample Testing:Improve sampling rate and reduce cost

COVID-19 Pooled Sample Testing:Improve sampling rate and reduce cost.

With the advent of autumn and winter, the possibility of a new outbreak of COVID-19 is increasing.

COVID-19’s large-scale community screening is the main means to cope with the recent outbreak of small-scale epidemics at home and abroad.

At present, New Coronavirus’s mixed sample nucleic acid detection has become a routine method to effectively enhance the screening and detection of nucleic acid in community population.

The pooled sample test of covid-19 increase the sampling rate and meet the growing needs of low-risk populations.

Virus transport medium,disposable virus sampling tube

What is a Pooled Sample Test?

“mixed detection”, that is, nucleic acid test of Pooled Sample.

On the one hand,it is a method to sample several people, such as 3 or 5 or even 10, and then put them into the same virus sampling tube.

On the other hand,pooled Sample means combining the same type of specimen from several people and conducting one NAAT laboratory test on the combined pool of specimens to detect SARS-CoV-2.

What is the significance of nucleic acid test in Pooled Sample?

COVID-19 Pooled Sample Testing Advantages

Because a virus sampling tube only puts one person’s sample, the cost will be very high, and the detection time is long, which is not suitable for large-scale nucleic acid detection.

In principle, the single sample sampling mode is only applicable to high-risk areas and key populations.

In order to improve sampling efficiency, shorten sampling time and reduce sampling cost. Multi Country selection of Pooled sample test scheme.

For example, when 5-in-1 mixed sampling test is used, the result is negative, which means that all five people are negative.

On the contrary, once positive or weak positive is found, it will be traced immediately.

Re collect single tube swabs for review, and then determine which of the 5 people is positive.

Therefore, the cost of 5-in-1 mixed mining is relatively low.

This also caused the 5-in-1 mixed sampling mode to be five times faster than the previous mode of using a virus sampling tube for a human sample.

One of the biggest disadvantages of sample merging is the decrease of associated test sensitivity.

Analyzing multiple samples in a single reaction effectively improves the flux, but it also dilutes a single sample and may reduce the weak positive signal from outside the detection limit.

In short, pooled sample testing is mainly used for large-scale screening to check asymptomatic coronavirus infected persons. It is suitable for large-scale testing projects such as schools, factories, units and urban areas. It has the advantages of efficient screening and resource saving.

Although reduced detection sensitivity is acceptable for screening services in asymptomatic populations.

However, When providing diagnosis for high-risk or symptomatic patients, we must give priority to the accuracy of the results.

The special preservation tube for Pooled Sample test uses medical grade PP as raw material, unique structural design and manufacturing process to prevent liquid leakage. And has the characteristics of high temperature resistance, high pressure resistance and high-speed centrifugation resistance.

Cell medical (Dongguan) Co., Ltd. produces virus sampling tubes of various specifications, both inactivated and non inactivated, disposable virus sampling tubes, pooled sample sampling tubes.
such as 1ml, 2ml, 3ml, 5ml, 10ml and other specifications.

Virus DNA / RNA sample preservation solution (inactivated or non)

I believe that my friends must be very curious when they first came into contact with this term. Virus DNA / RNA sample preservation solution, also known as cell preservation solution, virus transport medium or disposable virus sampling tube.

What is a virus transport medium?

First, the virus preservation solution is a liquid that immerses the sampling swab virus sample in the sampling tube and protects the detected substance (DND or RNA) of the virus.

It is mainly used for the collection, preservation and transportation of common virus samples such as New Coronavirus, hfmv, influenza virus and so on.

Researchers can use it to collect throat swabs, nasal swabs, or tissue samples from specific sites.

The samples are stored in a disposable virus sampling tube, which can be used for subsequent clinical experiments such as nucleic acid extraction or purification.

We divide virus transport media into two types, one is non inactivated and the other is inactivated.

The non inactivated type can protect virus protein and nucleic acid, preserve virus activity and facilitate culture and detection.

The inactivated type makes the virus no longer have physiological activity, lose infection and disease, and have fecundity, which can inactivate the virus.

Eliminate secondary infection and protect the safety of transportation and testing personnel.

Because the virus is a parasite, it cannot survive in vitro after sampling. If it cannot be detected in time, it needs to be stored in virus preservation solution.

In order to protect the security of virus detection environment and detection personnel, our virus inactivation preservation solution comes in handy.

Some friends may wonder if the inactivated type will inactivate the virus? How can we check it?

Don’t worry, the purpose of using inactivated preservation solution is to lyse nucleic acid.

Release nucleic acid and then detect nucleic acid through subsequent real-time fluorescent RT-PCR to judge whether the sample contains virus characteristic nucleic acid, that is, whether it is infected with virus.

The virus has a single structure and contains only one nucleic acid and protein. Therefore, the virus is detected when the characteristic nucleic acid is detected.

Then some friends will ask, since the detection is so simple, why do you need virus preservation solution? What role does it play?

Usually, after virus sampling, not all samples can be transported and stored at the sample collection place.

Therefore, we need to transport and retain the collected virus swab, otherwise the virus nucleic acid will degrade quickly and the nucleic acid cannot be detected.

Therefore, we need to add preservation solution to the sampling tube to prevent the virus nucleic acid from being degraded so quickly.

Cell Medical’s virus preservation solution allows viral DNA/RNA to be stored and transported at room temperature for 1 week without degradation.

After extraction using most commercial kits, the obtained DNA/RNA is of high quality and high yield, and can be used for various gene testing and analysis experiments, such as PCR and qPCR, while saving transportation costs.

Cell Medical’s inactivated virus storage fluid uses a small volume storage fluid compared to the large volume storage fluid of a traditional virus sampling tube, which avoids excessive dilution of the collected samples and increases detection sensitivity.

And our inactivated virus storage solution is so easy to use that you can take samples at home.

Moreover, our inactivated virus preservation solution is simple and convenient to operate. You can take samples at home.

Well, if you have anything you don’t understand or want to consult, please leave us a message.

Disposable virus sampling tube kit

The virus sampling tube consists of swab + sampling tube + virus preservation solution.

That is, flocked swab, virus sampling tube and virus transport medium.VTM

Why use a disposable virus sampling tube kit？

Virus is a very tiny organism, which is composed of nucleic acid and protein shell. Without its own metabolic mechanism, there is no protease system. Therefore, if the virus leaves the host cell, it cannot continue to survive. Such tiny creatures can bring us many diseases, such as RNA, influenza, HIV and H1N1 viruses. Because it has no cellular structure, the virus itself cannot replicate. Instead, it invades the gene into the host cell and replicates a new virus with the help of the latter’s replication system.

In order to maintain the activity of virus samples and prolong the survival time of virus in samples.

The sampling swab will be stored and transported in the preservation solution.

flocked swab_Disposable virus sampling tube kit

Brief introduction

1. In the current COVID-19 epidemic situation, virus sample collection is an important link in virus detection.

2. Disposable virus sampling tube kits can collect, transport, inactivate and store virus samples in specific parts of human body. (not available in the United States).

So what’s the difference between the non inactivated and inactivated virus sampling tubes?

about non inactivated and inactivated virus sampling Virus transport medium

In short, the non inactivated sampling tube can protect the protein nucleic acid of the virus, so that the sampled virus has its originality, better integrity and higher detection rate. In addition to nucleic acid detection, scientists can also use non inactivated samples in other virus research experiments.

Advantages:

★ easy to operate and use

★ add virus stabilizing components to maintain virus activity in a wide temperature range

And reduce the decomposition rate of virus (non inactivated type)

1. Low temperature non freezing storage, does not damage the shell of the virus, and is convenient for long-distance transportation.

2. Applicable to all kinds of swab samples, including oral swab, nasal swab, throat swab, etc.

★ it contains virus lysate and virus nucleic acid preservation solution, which can quickly lyse the virus

Release nucleic acid and stably store nucleic acid (inactivated type)

The inactivated sampling tube contains cleavage salt, which can destroy the protein of the virus. However, it can protect the nucleic acid of the virus, so that the virus has no infectious activity. The sampling virus in the inactivated sampling tube can prevent the risk of secondary infection and ensure the safety of transportation and testing personnel.

note

1. forbidden to directly contact the preservation solution with virus samples.

2. forbidden to infiltrate the swab with preservation solution before sampling.

3. only used for the collection, transportation and preservation of virus samples. It shall not be used beyond the expected purpose.

4. Before using this product, pay attention to the shelf life and whether the packaging is intact.

What are the covid-19 sampling tools？

Flocked sampling Swabs,VTM Kits,Viral Transport Medium,VIRUS Collection & Transport Kits,Saliva collection kit,Disposable virus sampling tube,Op swabs,Np swabs,etc.

Why use sampling tools？

At present, the global New Coronavirus epidemic has reached a critical stage. The most reliable means of rapid diagnosis is still positive for nucleic acid detection. There has been a great breakthrough in the diagnosis of COVID-19, but clinicians, especially the laboratory doctors, still face the following serious problems:

1. Safety of specimens

The majority of “angels in white”, especially the laboratory doctors, are always facing the risk of virus infection.

Although there are various protective equipment, the risk of infection will increase if we can’t ensure the safety of specimens. Therefore, it is very important to ensure virus inactivation and the safety of collected samples.

2. False negative test results

The existence of false negative puzzles the clinic and affects the accuracy of diagnosis. The biggest problem is sample collection and preservation. The New Coronavirus infection prevention and control program (Fifth Edition) has been published to collect nasal swabs, throat swabs, sputum, lower respiratory tract secretions, blood and feces. The incorrect way of collecting and storing samples will lead to the degradation of viral RNA and directly lead to the false negative test results.

Cell medical (Dongguan) Co., Ltd. provides the perfect solution for sampling tools.

√. Cell medical provides samples of swabs collected from various viral types including New Coronavirus (covid-19) and provides a perfect solution.

√ .It can quickly inactivate viruses including New Coronavirus, influenza A virus and many other viruses.

Requirements for protective packaging of sampling personnel: N95 and above protective masks, goggles, one-piece protective clothing, double-layer latex gloves, waterproof boot covers, etc. in case of direct contact with the specimen, the protective equipment shall be replaced in time.

2) Sample type: pharyngeal swab and nasal swab.

nasal swab_COVID-19 sampling tools

Pharyngeal swab collection method: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with a plastic rod swab with polypropylene fiber head

Nasal swab collection method: gently insert a plastic rod swab with polypropylene fiber head into the nasopalatine part of the nasal canal, stay for a moment, and then slowly rotate and exit. Take another plastic rod swab with polypropylene fiber head and collect the other nostril wall in the same way.

3) Specimen preservation: immerse the swab head into the tube containing virus preservation solution, discard the handle along the folding point of the sampling swab, and tighten the tube cover.

Notes

10 in 1 mixed sample detection virus sampling tube

Ten in one hybrid collection and detection technology is to collect 10 flocked swab samples collected by 10 people into a collection tube for nucleic acid detection. Once we find positive in the mixed collection screening, we will immediately notify the relevant departments to temporarily isolate 10 subjects in the mixed collection tube. Single tube swabs were collected again for reexamination to determine which of the 10 subjects was positive; If the test result is negative, it means that all ten samples are negative and the mixed ten people are safe.

Mixed detection greatly improves the detection ability of nucleic acid. Using this combination mode, the daily detection ability can be increased by 10 times without increasing human and material resources. It can carry out more screening and early diagnosis, strive to find patients one minute in advance, isolate patients one minute in advance, reduce transmission and save social costs.

Product overview:

① It is applicable to large-scale testing projects such as schools, factories, units and urban areas. It has the advantages of high screening efficiency and resource saving.

② The sampling tube for mixed sample detection of virus uses medical grade PP as raw material. Unique structural design and manufacturing technology prevent night leakage. It has the characteristics of no RNA enzyme, no DNA enzyme, no endotoxin, high temperature resistance, high pressure resistance and high-speed centrifugation.
