The recurrence of the new epidemic has made nucleic acid testing the most common topic of discussion, and many of you may have noticed the red tube to be put in after sampling the nucleic acid test swab, which actually has a professional name "single-use virus sampling tube", and is usually divided into inactivated and non-inactivated types. Single-use virus sampling tube.

What is the difference between inactivated and non-inactivated virus sampling tube application scenarios?

I. Non-inactivated virus preservation fluid sampling tube is mainly used in the CDC, research units and other units with special requirements for virus activity.

II. For nucleic acid (2019-nCoV) detection, most of the applications or inactivated virus preservation fluid sampling tube.

Inactivated virus sampling tubes containing guanidine salt preservation solution: mainly by adding protein denaturant - guanidine salt (guanidine isothiocyanate), so that the denaturation of proteins, denaturing lysis of the virus, to inactivate the virus, release nucleic acid to the preservation solution for the purpose of detection.

What are the advantages of inactivated lysis type single-use virus sampling tube:

1. Safer.

Virus lysis type preservation solution, containing a variety of virus inactivation components, efficient inactivation of viruses, to ensure the safety of transport and testing personnel.

2, more stable.

The preservation solution contains RNase inhibitory components to ensure the integrity of nucleic acid. Eliminate the appearance of false-negative results.

No need to store and transport at 2~8℃ after sampling, 48 hours at room temperature does not affect the quantitative nucleic acid results.

The nucleic acid in positive samples can still be detected when stored at room temperature for 7 days, saving the cost of virus sample storage and transportation.

3. More convenient.

Set of products, with our flocked swab, reasonable design, both to increase the safety of the operator and to ensure the stable adsorption and release of samples, the same operation can be collected once more samples.

Ltd. produces 10 mixed 1, 20 mixed 1 and other mixed test kits with the advantages of efficient screening and resource-saving, has been widely recognized by the market.
