Facing COVID-19 variation strain

Posted on 2021年9月7日2021年12月21日 by Dr. Lee

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

Rapid Antigen Test Kit specimen testing

Cell medical (Dongguan) Co., Ltd. is a comprehensive high-tech biotechnology company and an OEM factory of flocking swabs in China.We support custom production,our factory produces flocked swabs, pharyngeal swabs, nasal swabs, oral swabs,Rapid Antigen Test Kit, virus sampling tubes, transportation media, sample preservation solution and nucleic acid extraction kit. Our GMP factory was built in 2016,the factory has ISO13485 quality management system, CE, FDA and other qualifications.

Secondly, we should keep regular work and rest and keep learning.

Adhere to exercise and treat your body: regular work and rest, balanced diet, exercise and regular physical examination. After all, the body is the capital of revolution, and immunity is the first competitiveness.

Finally, if your physical condition permits, please vaccinate as soon as possible. For you, for your family and for our national peace and security.

In order to better prevent COVID-19 variation strain, Cell medical (Dongguan) Co.,Ltd. increases production and guarantees supply.

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

Firstly,before sampling, mark relevant information on the label of the sampling tube.

Secondly,use the corresponding sampling flocked cotton swab for sampling.

Then,after sampling, quickly put the cotton swab into the sampling tube, break the part higher than the sampling tube, and tighten the tube cover.

Finally,see the following for specific sampling methods.

a)Nasal swab: gently insert the sampling head into the nasopalatine part of the nasal catheter, stay for a moment, and then rotate it slowly to exit. Immerse the collected specimen into the liquid in the sampling tube, break the excess part and discard it, and tighten the sampling tube cover.

b) Pharyngeal swab: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with sampling head. Soak the collected specimen in the sampling solution, break the excess part, discard it, and tighten the sampling tube cover.

9.[precautions]

1. After collecting pathogenic bacteria samples, we should completely insert the disposable sampling flocked cotton swab into the preservation solution to retain pathogenic bacteria to the greatest extent.

2. The collected samples must be fresh and sent for examination in time to avoid the death of pathogenic bacteria.

3. Forbidden to use products with damaged packaging and expiration date to prevent pollution.

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;
