When samples are collected with ordinary virus sampling tubes, the virus itself quickly dissolves outside the body, affecting subsequent testing. For new coronaviruses, a virucidal solution needs to be added during transport, so let's learn more about the types of virus sampling tubes below!
For different testing purposes, it is necessary to choose different virus sampling tubes. The two types of virus sampling tubes that are widely used today each have their own characteristics.
Inactivated virus sampling tube: high concentration of guanidine salt can instantly and effectively inactivate the virus and prevent staff from re-infecting the virus. Mainly nucleic acid extraction decomposition solution modified from the virus decomposition solution.
When collecting new crown specimens, the collection of new crown specimens, sent to the laboratory as soon as possible to check, within 24 hours can be checked in 2 ~ 8 preservation, can not be immediately checked in -20 below preservation, to ensure that the collected specimens within a week to the corresponding laboratory, during this period try to freeze this product without sampling, 2 ~ 35, sealed, shaded preservation, valid for 12 months, can effectively save transportation costs.
Inactivated virus sampling tube: mainly based on the virus preservation solution that has been improved to maintain virus activity, in order to maintain virus activity and add the base solution and nutrients suitable for virus survival. It is not easy to decompose and greatly maintains the integrity of the virus sample.
This product can maintain virus activity and virus nucleic acid integrity in vitro and maintain the protein shell of the virus. In addition to nucleic acid extraction and detection, this preservation solution can also be used for virus culture, isolation and antigen detection.
Virus sampling tube is used for microbial collection and delivery tube for influenza virus, hand-foot virus, measles rubella and other viruses collected in a matching collection and delivery of centrifuge tubes, virus collection tube consists of a collection tube containing wipers and preservation solution. Also known as specimen delivery tube, has now become a commercial product.
The main use of virus sampling tube;
Virus sampling tubes can be used by disease control departments and clinical departments for the monitoring of infectious pathogenic microorganisms;
It can be used for nucleic acid extraction and later virus isolation of influenza virus, hand, foot and mouth virus, rubella and measles virus samples from clinical patients;
In addition, it is also used for sampling of mycoplasma, chlamydia, and plasma of anthelmintic.
Virus sampling tubes can be used for the collection and short-term transportation of avian influenza viruses in the external environment.
Virus sampling tubes can be used for daily testing and sampling of poultry, pigs and other animals
Virus sampling tubes can be used for short-term storage of virus samples. (stored at 2-8 for 48 hours) pending necessary cell culture.
Virus sampling tubes can be used for long-term storage of virus samples (up to 1 year at -70~-196) for necessary cell culture.
Virus sampling tubes can be used for the collection of clinical respiratory virus rapid test kits.
Virus sampling tubes can be used to carry site-specific tissue specimens from the sampling site to the testing laboratory; however, please note that for novel coronaviruses, customers should select virus sampling tubes from the regular manufacturer according to the newly developed technical specifications for new coronavirus assays. Perform the necessary cell culture. Customers can choose different sizes of virus sampling tubes according to the needs of the experiment. It can effectively avoid staff re-infection and can be stored at room temperature. At the same time, with small volume preservation, biological production of disposable virus sampling tubes (inactivated type) is easy to use, prevent specimens from being over-diluted, facilitate nucleic acid extraction, and can improve detection sensitivity.
The above is the type of virus sampling tube, for more information, please feel free to contact us!
