COVID-19: RT-PCR Kit for detection of RdRP, E, N and RNaseP genes

There are many people who want to know if they are infected with COVID 19. And the fact that we can be carriers of the virus and not show any symptoms, is especially delicate when we work in sectors where we come into contact with many people hence the importance of having a COVID-19: RT-PCR Kit.


The RT-PCR KIT is an analysis kit that allows us to know if a person is infected with coronavirus. Remember that you have to be very scrupulous when selecting a virus with these characteristics since there are four genes in the Coronavirus family and you have to choose the test that best suits each one of them.

Each of the genes in the coronavirus family is known by the name of one of the letters of the Greek alphabet. In this case with the first four: alpha, beta, gamma and delta.

Corona alpha and beta viruses can cause disease in both humans and animals, while others, such as the gamma and delta coronaviruses, only infect animals.

Well, the new coronavirus (specifically named as COVID-19) belongs to the beta gene family and 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. A disease that months later has become a pandemic and affects the population of the entire planet, given the speed and ease with which it spreads.

Hence it is especially important to diagnose an infection quickly, as there are no vaccines or antivirals approved for prophylactic or therapeutic purposes. What can cause death in case, above all, that the infected person has diseases related to chronic respiratory tract.


Well, to be able to detect it in time and catch the disease at its beginning, there is nothing better than to test people with symptoms (or who have been close to those who have had it). And to carry it out the best is to have the most reliable test on the market: the COVID-19: RT-PCR Kit, a test that is validated by the Carlos III Institute (to which the National Center for Microbiology belongs)

The guiding principle of this kit is that you can detect the new coronavirus using the RT-PCR probe method in real time, through the reaction of the specific primer and the fluorescent probe in the sample.

In addition, this test can also detect the RdRp gene and the E gene, markers for the detection of new coronaviruses, so it is also a new way of anticipating the infection of other similar genes. In addition, the N gene suggested by the US CDC is included. and the RNaseP gene.

Its intended use is using sputum that accumulates in the lower airways, bronchoalveolar lavage fluid (BAL), or nasopharyngeal smear (NS) and oropharyngeal smear (OS) collected simultaneously in the upper airways.

DNA extraction kit from saliva at Durviz

Saliva is a substance that can give us a lot of information about a person’s state of health. At Durviz we know how interesting and reliable the data that can be extracted from a person’s saliva is, which is why we have products that facilitate its analysis. It is very important to have first-class products that help us to preserve the saliva sample without any contamination..

For this reason, in our virtual store we have products such as the Real Saliva Collection and Transport, one of the most popular on the market. This kit provides a fast and safe all-in-one method for the collection, stabilization and transport of saliva samples at room temperature.

Its main characteristics are the following:

  • Easy collection, transport and processing of saliva samples.
  • Painless collection, and non-invasive (as opposed to other systems where samples are taken from patients).
  • Allows saliva samples to be stored for 2 years.
  • The saliva kept in this kit is preserved and ready to be sent.
  • It allows the subsequent isolation of DNA making it an element of excellent quality and integrity.

The operation of this kit is very simple and requires few steps, which speeds up the work in the laboratory. The first thing to do is to collect the saliva samples. This is done by simply spitting into the collection funnel that has been assembled with a collection tube. This eliminates almost 100% of the possibility of contamination.

After collecting 2 millilitres of saliva (container capacity), the content of the saliva preservation solution is added and mixed with the extracted saliva. Finally, the saliva collection tube is sent to the laboratory for further isolation and DNA analysis.

This is usually recommended with the Real Pure saliva kit, which follows the same protocol and
that you get unbeatable results. The saliva samples are kept stably for more than one year at room temperature and more than 2 years if these same samples remain within the following temperature range: -20ºC or -80ºC.


For best performance, the manufacturer also recommends the following for the
when saliva samples are collected and preserved:

1. It is advisable not to eat, chew gum, drink or smoke during the 30 minutes before the saliva sample is taken.
2. It is advisable to wash out the mouth with water and wait for 10 minutes.
3. It is better if the patient rubs his cheeks and the palate with his tongue before collecting the sample. This gesture is sufficient to stimulate the secretion of saliva.
4. Before starting to collect the sample, it is convenient to place the funnel in the saliva collection tube. Then just spit the saliva into the funnel until the liquid (not including the bubbles) reaches the 2 milliliter line in the collection tube. If there are excess bubbles, they should be removed by gently tapping the tube on a hard surface.
5. Remove the blue cap from the saliva preservation solution.
6. Add the saliva-conserving solution to the collection tube.
7. Close the saliva collection tube tightly to avoid accidents or contamination.
8. Shake for 15 seconds to thoroughly mix the products with the saliva.
9. Once this procedure is done, the saliva sample is now preserved and ready to be stored, shipped or processed.

For all these reasons, this new model of Saliva Collection Kit is one of the most popular on the market. And one of the most popular among laboratory professionals.
