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.
