As the first step of nucleic acid testing, the importance of sample collection and storage is undoubted, and choosing the right virus collection tube can make nucleic acid testing twice as successful!
Ltd. is approved to market for the collection, transportation and storage of viral samples, providing effective assistance for nucleic acid extraction and subsequent testing.
The sample preservation solution of this product contains high concentration of guanidine salt, which can lyse and inactivate the virus in the sample by mixing with the collected sample thoroughly. It can effectively solve many problems of sample transportation, virus inactivation and nucleic acid preservation, providing source protection for nucleic acid detection.
Product features:
One, a variety of options
Meet the different requirements of molecular testing and gene sequencing
◆ Multiple models, multiple specifications, multiple combinations;
No swab, nasopharyngeal swab, oropharyngeal swab, double swab are available;
◆ Preservation solution 3mL~6mL, single test, five mixed one, ten mixed one all meet.
Second, safe and reliable
Can quickly inactivate the virus, to eliminate secondary transmission of infection
◆ Preservation solution contains high concentration of guanidine salt, so that the virus in the sample cleavage inactivation, to protect the safety of personnel;
◆ Sterile swabs are packed independently to ensure zero contamination in the sampling process.
Easy to use
The virus RNA can be transported at room temperature and stored at 37℃ for 1 week without degradation, with high stability.
No need for cold chain transportation, 2-30°C room temperature storage and transportation is sufficient, no special environmental requirements;
◆ The virus nucleic acid can be preserved stably by folding the swab in the preservation solution immediately after sampling.
Sample collection
Nasopharyngeal swab collection process
Remove the secretions from the surface of the anterior nasal aperture. Insert the swab gently and slowly through the nasal cavity to the pharynx. When resistance is encountered, the swab reaches the nasopharynx and is removed by gently rotating it for a few seconds and placed in a tube of sample preservation solution.
Oropharyngeal swab collection procedure
The tongue was fixed with a tongue depressor, and the mucosal cells were collected by repeatedly wiping the swab 3 to 5 times across the tongue root to the posterior pharyngeal wall and tonsillar crypt and lateral wall. The swab was removed gently, avoiding touching the tongue, pendulous oral mucosa and saliva, placed in a sample preservation fluid tube, the swab was broken at the easy-to-break cut-off point of the swab rod, and the tail was discarded and the cap was tightened.
Specimen preservation
Specimens can be used for testing immediately after collection and can be stored for at least 7 days at 2 to 37°C and for a long time below -70°C. Samples should not be repeatedly frozen or thawed.
