Virus transport and preservation medium: BIOCOMMA

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.

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.

Real Saliva Viral. Saliva samples.

Real Saliva Viral: Brochure

Real viral saliva is a simple and practical kit that aims to bring speed and practicality to laboratory work. This novel product provides a safe and fast procedure for collecting, stabilizing and transporting saliva samples. Something fundamental especially now that large amounts of testing are being carried out by COVID 19. A procedure in which it has proven to be highly effective, allowing a large amount of sample collection to be made without any of them being harmed.

An all-in-one that allows us to work with 1 ml saliva samples at room temperature, allowing viral DNA/RNA to be stabilized without any problem. To do this, this product uses its own solution (contained in the kit itself) that inactivates viruses and prevents the degradation of nucleic acid in samples collected with our system. In this way, non-infectious samples are properly preserved for safe handling and sent.

The saliva samples we treat with this Real Saliva viral substance are kept at room temperature for a long period of time. Thus, in the case of DNA we have to talk about a period that extends over an entire year; and in the case of one-stage RNA that goes up to a month).

However, this is not the only advantage in or that of conservation. Saliva samples can also be frozen (-20/-80°C) for extended periods. A larger stage than other saliva testing kit offers.


Operation of a Real Saliva Viral

The way we can use this kit is very simple and is summarized in the following steps:

  1. Before removing the sample, people should be warned not to eat, drink, smoke or chew gum. Unless they haven’t done so 30 minutes before the sample was collected. Otherwise, it will be very difficult to get 1 ml of saliva. An extraction that can take several minutes in normal situations and that in the cases referred extends over time.
  2. The funnel must be inserted into the sample collection tube. It is advisable to rub the cheeks with the tongue and teeth for stimulation of saliva secretion.
  3. Collect saliva until 1 ml line level is reached.
  4. Remove and discard the funnel.
  5. Remove the cap from the saliva preservation solution and add all its contents to the collection tube.
  6. Close the sample collection tube with its green cap.
  7. Shake the tube vigorously for 15 seconds to mix saliva well with saliva preservation solution. At this point we must avoid unsolving saliva lumps.
  8. The saliva sample is already preserved and ready for storage, shipping and processing.

Real Viral Saliva Apps

With all this Real viral saliva is much more effective than other similar products on the market, and they also offer the possibility to store saliva samples in the right way, for further analysis or treatment.

This kit presents all these application possibilities:

– It is a product specially designed for the collection, storage and transport of viral samples of 1 ml of saliva.

– Its substance inactivates microorganisms and viruses to enable safe and easy transport and handling.

Can be used to isolate human genomic DNA or viral DNA/RNA. In both cases you get excellent results.

Allows the sample to be transported at room temperature without adversely affecting it.

Facilitates the preservation of total DNA, including viral DNA, at room temperature (4º-25ºC) for an entire year, without any alteration.

Allows total RNA, including viral RNA, to be preserved at room temperature (4º-25ºC) for an entire month.

It is compatible with most of the DNA and RNA isolation methods on the market although the company recommends that the products and methods they manufacture be used as they are of very high quality standards and their greater efficiency has been proven in this regard.
