After collecting specimens using virus sampling tubes, conventional specimens cannot be tested immediately by PCR. It is usually necessary to transport the swab sample together with the specimen. The virus itself will rapidly lyse in vitro and interfere with subsequent testing. When transporting, virus preservation solution must be added. The following nucleic acid virus sampling tube manufacturer takes you through the two types of virus sampling tubes: inactivated and non-inactivated.
Nucleic acid virus sampling tubes
For different testing purposes, different virus sampling tubes are required. The two currently widely used virus sampling tubes have their own characteristics. In order to meet different testing requirements and different virus testing laboratory conditions, it is usually necessary to sample different virus sampling tubes.
Inactivated virus sampling tubes: mainly virus lysis preservation solution modified from nucleic acid extraction lysate. It contains high concentration of guanidine salt during sampling can effectively inactivate the virus, which can effectively prevent the operator from re-infecting the virus. And it can be stored at room temperature for a relatively long time, thus saving the cost of virus sample preservation and transportation.
Non-inactivated virus sampling tubes: mainly based on improved transport media-based preservation solutions for virus adherent solutions. Non-inactivated virus sampling tubes maintain virus activity and the integrity of antigens and nucleic acids in vitro, maintain the protein shell of the virus and are less susceptible to differentiation, and maintain the originality of the virus sample to a large extent. In addition to nucleic acid extraction and detection, the storage solution can be used for virus culture, isolation and antigen detection. However, strict cryogenic temperatures are required for long-term storage after sampling.
Virus sampling tube manufacturer
As can be seen, different virus sampling tubes need to be selected depending on the conditions. However, it should be noted that whether inactivated or mis-inactivated, virus sampling tubes must be rigorously inactivated and sterilized prior to sampling to ensure that there are no other microorganisms in the tube, which could lead to virus differentiation. Other or other effects after sampling lead to false detection. The use of poor quality collection tools or preservation solutions after swab sampling will affect subsequent test results and can even lead to false positives for misdiagnosis. Therefore, it is necessary to choose a nucleic acid virus sampling tube manufacturer.
Ltd. developed single-use virus sampling tubes, which are suitable for the collection and transfer preservation of virus samples of clinical new coronavirus, influenza, avian influenza, hand, foot and mouth disease, measles, etc.. It is also suitable for specimen collection and transportation of Chlamydia, Mycoplasma, Mycoplasma solium, etc. Samples are usually collected in the human mouth, throat, nasopharynx, anus and other parts of the body. Sampling swabs are flocked swabs. After sampling by conventional fiber swab, the sample is easily intercepted by the interstitial space within the fiber mass, i.e., the sample is penetrated, diluted, and intercepted within the fiber. The flocked swab adopts a unique jet implanted nylon fluff book technology, which has outstanding sample collection and release capability, and the release rate can reach 90%, much higher than fiber swab. Unique breakable design, no tiny debris generated during fracture.
