Nasal Sampling Foam Swab
Matters Needing Attention
The virus is composed of a nucleic acid molecule and a protein or only a protein, which is small in size and simple in structure. Because there is no cell structure, the virus itself can not replicate, but the nucleic acid gene into the host cell, with the help of the latter replication system to replicate new virus. After collection of virus samples, in order to maintain the activity of virus samples, prolong the survival time of viruses in the samples, or inactivate viruses with lysate, only some important components of the virus (such as nucleic acid and antigen protein) are preserved and transported in the preservation solution.
The disposable virus sampling tube is composed of sampling tube, cap, VTM preservation solution and / or sampling swab.
[Storage conditions and validity]
Storage conditions: normal atmospheric temperature
Note: after the sample is embedded in the sampling tube, it generally needs to be stored and transported at 2-8 ℃.
The specimens should be transported to the corresponding laboratory within 3 working days after collection, and the storage temperature should be 2-8 ℃; if they cannot be sent to the laboratory within 72 hours, they should be stored at – 70 ℃ or below, and the specimens should avoid repeated freezing and thawing.
