GST sampling tube automatic production line manufacturers know that many people will have questions, we usually do the new crown nucleic acid rapid test sampling, swab put into a small tube to save, and then sent to the laboratory to do the new crown nucleic acid rapid test. So, this small tube actually put in what liquid it?

　　It turns out that the new crown nucleic acid rapid test sampling tube is divided into two types containing guanidine salt and without guanidine salt.

　　1. inactivation type preservation solution, it belongs to the virus lysis type preservation solution, the base solution is a modified nucleic acid extraction lysis solution, the composition of guanidine salt, Rnase inhibitor. It can be stored at room temperature. It has the following advantages.

　　It saves the cost of virus sample preservation and transportation.

　　Contains a high concentration of guanidine salts that can efficiently inactivate the virus and effectively prevent secondary infection of the new crown nucleic acid rapid test operator.

　　Can be stored at room temperature for a relatively long time, saving the cost of preservation and transportation of virus samples.

　　2. non-inactivated preservation solution, which belongs to the virus maintenance fluid type preservation solution. The base solution is a transport medium based modified solution, the components are Hanks liquid base, gentamicin, fungal antibiotics, BSA (V), cryoprotectants, biological buffers and amino acids, etc.. It must be strictly cryogenic. Advantages are.

　　Maintains the in vitro activity of the virus and the integrity of the antigen and nucleic acid.

　　In addition to being used for rapid detection of new crown nucleic acids, it can also be used for virus culture, isolation, and antigen detection.
