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.

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

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.

COVID-19 sampling tools help SARS-CoV-2 precise diagnosis!

Cell medical (Dongguan) Co.,Ltd. monthly production of millions of virus sampling swabs and VTM kits helps epidemic prevention and control.

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.

√ .preservation solution: preserve RNA to prevent degradation.Disposable virus sampling tube.

√ .safety guarantee: vertical design, sampling and preservation in one step to reduce personnel exposure.

Sampling steps of new virus collection tube

1) The collection personnel shall be qualified through biosafety training and have corresponding experimental skills. 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

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

The tube containing virus preservation solution another name isvirus sampling tube.

Virus preservation solution is also called virus transport medium.VTM.

New Coronavirus nucleic acid detection steps

1、 The specific operations are as follows

1. Virus sampling:

Take the patient’s saliva sample or nasopharyngeal flocked swab sample, and save the virus sampling tube.Virus preservation solutions commonly used in disposable virus tubes include inactivated and non inactivated types. The following are two models of virus transport medium:

1) Inactivated type: the inactivated virus transport medium characterized by killing the virus and retaining nucleic acid fragments. Application:detect COVID-19, influenza virus, hfmv and influenza A.

2) Non inactivated type: the non inactivated virus transport medium does not contain lysate. It can retain the activity and integrity of pathogens.Application:virus culture and reproduction to make the detection results more accurate.

2. Nucleic acid extraction:

Extract the genetic material from the patient’s sleeping fluid or nasopharyngeal swab sample. If a patient carries a virus, there will be RNA of the virus’s genetic material in the sample. Sampling personnel should pay attention to prevent RNA degradation when extracting RNA. At the same time, the extracted DNA shall be stored at – 20 ℃, and the RNA and DNA requiring long-term storage shall be stored at – 70 ℃ or liquid nitrogen.

3. Reverse transcription synthesis of cDNA:

reverse transcription of RNA in the extract, reverse transcription of RNA into cDNA, reverse transcription of cDNA synthesis reaction, using reverse transcription primers, dNTPs, reverse transcriptase, RNase inhibitor and DTT. Buffer, an appropriate amount of ultrapure water without RNA / DNase and RNA template. We propose to use commercially available RT-PCR one-step reagent for one round amplification of di.

4. PCR amplification reaction (nested PCR amplification method with secondary amplification):

Use specific primers of virus cDNA for PCR amplification in an amplification instrument. Nested PCR amplification using secondary amplification.

5. Result analysis and judgment:

If the DNA band of the virus is amplified, it is determined that the virus exists in the patient; If no DNA band is amplified, it is determined that the sample taken by the disease has no virus.

2、 Experimental precautions:

① We should set up two positive controls and two negative controls for each test. Only when the positive control enlarges the expected fragment, the negative control does not enlarge any fragment, and the results of two parallel samples are consistent.We can determine the nucleic acid positive or negative reaction results.

② Nucleic acid test is positive: if nucleic acid is positive, we should repeatedly collect samples for retest. If the retest result is nucleic acid positive, we can confirm that the sample result is nucleic acid positive. If the retest result is nucleic acid negative, the nucleic acid test result is uncertain.

Facing COVID-19 variation strain. How should we deal with it？

What are the variant strains of COVID-19?

The variation of COVID-19 B.1.621 was first confirmed in Columbia in January this year. The World Health Organization named it Miao strain and recently listed it as a mutant strain that needs attention. Its influence level is lower than that of the delta strain. Preliminary data show that the Miao strain is similar to the beta strain and will weaken the effectiveness of the antibody.

At present, there are four variants defined by who as “needing attention”, including alpha, beta, gamma and delta. And five variants “needing attention”, including ETA, iota, kappa, lambda and mu.

How should we deal with it？

Weightier than Mount Tai, I think the most important thing about this new crown epidemic is: life is above everything else and responsibility is heavier than Mount Tai.

We often ask: where is the value of life? After this epidemic, we answer is: responsibility.

A person and an enterprise must have a sense of responsibility before their life can be valuable. If a person is not responsible and has no sense of responsibility, his life is worthless.

First, Let’s do a good job in personal protection. Don’t worry too much.

As the general public, we can prepare some masks, medical goggles,Rapid Antigen Test Kit,New Coronavirus test kits and so on.We advocate new crown nucleic acid testing at home

What is the saliva collection kit used for?

Used for sampling, transporting and storing saliva samples.

Saliva collection kit consists of a saliva funnel (with collection tube) and a test tube with 2ml cell preservation solution. It is used to collect salivary DNA / RNA samples for virus PCR analysis. The average yield of RNA from 2ml saliva sample was 110 μ g. But the output may be 15 μ G to 300 μ G.

DNA / RNA was then isolated from human saliva samples for nucleic acid detection. Including the detection of COVID-19.

The biggest advantage of the saliva collection kit is that it is convenient and direct. Even the elderly and children can easily collect saliva into the test tube. Collecting saliva DNA / RNA samples allows direct viral PCR analysis without additional steps to process saliva collected using the saliva collection kit.

The saliva collection kit is very suitable for home and commercial use.

 

How to use saliva collector?

Clean the mouth:30 minutes before collecting a saliva sample, please wash away the debris in the oral cavity with absorption.

1: install the collecting funnel on the collecting pipe and spit saliva into the collecting funnel until the saliva reaches the filling line of the collecting pipe.

2: hold the collecting tube vertically with one finger and close the funnel cover with one hand.

3:Open the DNA preservation solution tube and unscrew the tube capand pour the DNA preservation solution into the salivary collector.

4: hold the collection tube vertically and rotate it gently to separate it from the collection funnel.
