If you are looking for a means of transport and preservation of viruses, the BIOCOMMA company has a virus transport and presenvation medium. product that at Durviz we put at your fingertips. That will solve many of the infrastructure and distribution problems of your laboratory. So that you can relate to him we have written this article in which we expose the main characteristics of this product.

Virus transport and preservation medium: the BIOCOMMA proposal

The BIOCOMMA company has designed a solution that allows any virus sample to be inactivated in time to prevent it from being infected by aerosol. It is also a product that protects RNA from degradation.

Its main components are: HBSS, glycerin and guanidine salts.

It is a product that is applicable for the collection and transport of samples of: clinical influenza, avian influenza, HFMD, measles. And other virus samples as well as mycoplasma, ureaplasma and chlamydia. Although it can also be used with other samples.

With this means of transport, in addition, two types of sampling can be performed: Nasal swab or throat swab. We will choose the most suitable one.

With this means of transport, in addition, two types of sampling can be performed: Nasal swab or throat swab.

BIOCOMMA: Operation

The operation of this BIOCOMMA proposal is very simple and intuitive. All you have to do is follow the following steps so that our laboratory samples are perfectly protected from any possible contamination. They are as follows:

  1. Write the sample information on the label before sampling.
  2. Depending on the purpose of the analysis, the swab must be used in one way or another to collect samples from the corresponding parts. For this, it is enough that we put the swab in the conservation solution immediately after taking samples, break the swab rod and close the lid firmly. Of course, you have to be careful with possible problems that may appear when handling it. For example, the product is a clear, colorless liquid. If the properties change, for example it turns yellow, it should be discarded. It should also be noted that the liquid in the sampling tube is the medium for transport. The swab cannot be submerged prior to sampling.
  3. Once the samples we want to analyze have been taken, they must be transported to the laboratory within 2 working days after collection. To do this properly, the storage temperature should be 2-8 ° C. If this cannot be done, the samples should be stored at -70 ° C or less; and ensure that the samples are delivered to the laboratory within a week. Repeated freeze-thaw cycles should be avoided.

With one exception to note: samples used for virus isolation and nucleic acid detection should be processed as soon as possible.

 

Biocomma Transport: Indications

Like all laboratory products, it has been conceived for a specific purpose. Hence, it has some specific indications. Some of the most prominent are the following:

  1. It is not a product suitable for internal or external use in humans or animals.
  2. Must be handled with care as it can cause serious events if swallowed; it is irritating to the eyes and skin. If accidentally splashed into the eyes, rinse them with water. It is also advisable to maintain ventilation during use to avoid possible poisoning.
  3. Residues of the sample collection solution must be sterilized.

With all this, BIOCOMMA’s means of transport and conservation will work perfectly and will allow us to carry out our work more efficiently and with a smaller margin of error in the results. If you want to have it in your workspace, contact us and we will tell you about it.

Detection of COVID19 in real time with LiliF COVID-19

/0 Comments/in /by

Detection of COVID19 in real time is possible with LiliF COVID-19. A very fast and highly efficient test that allows us to detect the presence of COVID 19 in the person undergoing the test.

 

What is the LiliF COVID-19 test

The LiliF real-time COVId detection test is a test that uses an RT-PCR probe. This test can detect the new coronavirus using the real-time RT-PCR probe method, through the reaction of the specific primer and the fluorescent probe in the sample.

So far, it has been proven that this test can detect the RdRp gene and the E gene, which are markers for the detection of new coronaviruses. In addition, this test also includes the N gene suggested by the US CDC and the RNaseP gene.

Unlike other similar tests that we can find on the market, this kit provides the necessary components to perform the RT-PCR separately. And all this being able to use the consumable selected by the user and being compatible with any thermal cycler.

Remember that this kit contains everything you need, you should not mix it with any other product other than it.

 

Detection of COVID19 in real time with LiliF COVID-19

For its correct operation, sputum in the lower respiratory tract, bronchoalveolar lavage fluid (BAL) or nasopharyngeal smear (NS) and oropharyngeal smear (OS) collected simultaneously from the upper respiratory tract of the person to be analyzed is necessary.

The entire process must be done in a clean bench to ensure that there is no contamination that can affect the final result.

For this, the kit includes a swab that allows the collection of these samples.

Although its operation is simple, it is recommended that its manipulation be carried out only by specialized personnel. Including the toilet. Otherwise we could get some alteration of the result, due to bad handling. In addition, during its handling it is convenient that we protect ourselves with masks. This way we will avoid spraying when opening the lid.

 

COVID19 and other coronaviruses

At this point, it must be remembered that so far a total of four genders have been identified in the Coronavirus family. They are known as alpha, beta, gamma, and delta.

The alpha and beta corona viruses can cause disease in both humans and animals. While other types such as gamma and delta coronaviruses only infect animals.

The new coronavirus (popularly known as COVID-19) belongs to the beta. Hence, it is one of the new infectious coronaviruses that infects the human body as a pathogen of massive pneumonia that occurred in Wuhan, Hubei (China) in December 2019. And that has subsequently spread throughout the world, being considered a pandemic a few months after the first case was detected.

Therefore, it is very important to diagnose an infection quickly. Since, at the moment, their vaccines are not available to everyone or are in a trial period. And that its reliability is not one hundred percent; and even that its administration is carried out in two phases that have months of difference between both.

It should also be noted that there are no antivirals approved for prophylactic or therapeutic purposes.

However, the choice of these tests must be done appropriately. Well, there is a wide offer on the market, and it is necessary to know them before purchasing them. For this reason, at Durviz we have developed this product. A high-quality, simple test that contains everything we need to perform the test and that will surely help us to obtain a reliable result.
