virus sampling tube 10 in 1 mixed sample detection

Posted on 2021年9月1日2022年3月22日 by Dr. Lee

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.

③ 10ml sample preservation solution (VTM solution) is pre installed in 50ml sampling tube for 10 person mixed sample detection.

④ The head end materials of virus sampling swab include flocking, polyester fiber, rayon, etc.Produced by special process, it has no DNA / RNA, no RNA enzyme and no DNA enzyme. It has the characteristics of high collection rate, high release rate, convenient operation and no sundries. The sampling success rate and detection rate are greatly improved.

⑤ Biosafety bag: for preservation and transportation after sample collection to prevent accidental leakage and improve safety.

⑥ Each set of virus sampling tubes includes: 1 sampling tube pre loaded with virus preservation solution, 10 individually packaged swabs。

Product advantages:

Safer.

Virus lysis buffer contains a variety of virus inactivating components, which can inactivate the virus efficiently and ensure the safety of transportation and testing personnel.

More stable.

The preservation solution contains RNase inhibitor to ensure the integrity of nucleic acid and prevent false negative results. There is no need for storage and transportation at 2-8 ℃ after sampling, and the nucleic acid quantitative results will not be affected after being stored at room temperature for 48 hours. The nucleic acid in the positive sample can still be detected after the virus is stored at room temperature for 7 days, which saves the storage and transportation cost of virus samples.

More convenient.

Our self-developed sample tube and flocked swab are combined into a set of products, which not only increases the safety of the operator, but also ensures the stable adsorption and release of samples, so that more samples can be collected in the same operation.

Nylon flocking swab This design ensures the maximum adsorption and release of samples, and the same operation can collect more samples than other swabs. Special design – easily broken groove

Cell medical (Dongguan) Co, Ltd.,Take you to know the virus sample preservation solution.

Virus sample preservation solution,also known as disposable virus sampling tube.When we first came into contact with this term, we must be very curious.

However,what is DNA / RNA virus sampling tube？

First of all, virus sampling tube is a liquid that protects the tested substance of the virus by immersing the sampling swab virus sample in the sampling tube. Currently, it is mainly used for the collection, storage and transportation of common virus samples such as COVID-19, HFMV and so on. Medical workers can take tissue samples from the throat or specific areas using throat swabs and nasal flocked swabs. Samplers then store the samples for subsequent clinical trials such as nucleic acid extraction or purification. The virus and related samples can be stored at -70℃ or liquid nitrogen for a long time.

Usually,we divide the virus storage solution into two kinds. the non-inactivated virus storage solution and the inactivated virus sampling tube. The non inactivated type can protect viral proteins and nucleic acids. Maintain virus activity and facilitate culture and detection. Although the inactivated type can make the virus no longer have physiological activity, lose infectivity and pathogenicity, and have the ability to reproduce. Inactivate the virus, eliminate secondary infection,and protect the safety of transportation and testing personnel.

disposable virus sampling tube

About inactivated sample preservation solution.

There may be a small partner who will question whether the inactivated type will inactivate the virus? How do you check it? Don’t worry, the purpose of using inactivated virus sampling tube is to lyse nucleic acid and detect nucleic acid by subsequent RT-PCR.

After extraction with most commercial kits, the quality of DNA or RNA obtained is good and the yield is high. So,it can complete various gene detection and analysis experiments, such as PCR or qPCR, and save transportation costs.

It is suitable for COVID-19, hfmv and other common virus samples.

About inactivated sample preservation solution.

The virus preserved in non inactivated virus sampling tube has better integrity and higher detection rate. Researchers use it for scientific research, including nucleic acid testing.
Cryogenic storage without freezing, does not destroy the virus shell, easy long-distance transportation;
Application:H1N1 influenza virus and any other Virus swab sampling;
The antibiotics in the preservation liquid can effectively prevent bacterial and fungal infection;

What is antibody testing

Posted on 2021年8月19日2021年8月19日 by Dr. Lee

What is antibody testing

Before explaining this method, let’s first understand what antibodies are.

The rapid immunoglobulin M (IgM) test paper developed by Chinese academicians is not only a remedy for false negative sampling, but also a method for detecting antibodies.

After the virus invades the body, it likes to kill directly into the cell and hide in it to copy its offspring crazily.

Of course, before entering the cell, B lymphocytes (a kind of white blood cells) find some viruses. B cells are activated and release a large number of antibodies. These antibodies bind to the virus, make the virus lose its ability to invade, and then phagocytes destroy the virus. We call this process humoral immunity.

The antibody is fast and powerful, but the disadvantage is that it can not enter the cell to kill virus. In short, antibodies can reduce the number of viruses in body fluids and prevent more cells from being infected.

There are 5 kinds of antibodies, namely IgM, IgG, IgA, IgD and IgE, with different characteristics and specialties.

When the body is stimulated by COVID-19, IgM will appear in a week or so. Based on this, by detecting whether the IgM in the human body increases significantly, we can indirectly identify whether the human body is infected or not.
