Due to the impact of the epidemic, the arrival of Spring Festival, nucleic acid detection has become our normal travel permit. This also led to a sharp increase in the market demand for virus sampling tubes and virus retention solutions. With demand, there will be supply naturally, which leads to a lot of business information. The variety and quality of the products are also uneven. How to buy regular and guaranteed virus sampling tube and virus preservation solution? This is the voice of every purchaser.

Disposable virus sampling tube: (sampling swab + virus storage tube + virus preservation solution)

Sampling swab: the sampling swab directly contacts the sampling part, and the material of the sampling head is closely related to the subsequent detection. The sampling swab head should be made of polyester (PE) synthetic fiber or rayon (artificial fiber), calcium alginate sponge or stick swab (including bamboo swab) cannot be used. The material of swab head cannot be cotton product, because the fiber of cotton has strong adsorption on protein and is not easy to elute into the subsequent preservation solution; however, the stick or bamboo stick containing calcium alginate and wood components is soaked after breaking The bubble also adsorbs protein in the preservation solution, and even inhibits the subsequent PCR reaction.

Virus preservation tube: it is mainly to prevent leakage, can we find such a storage tube? When tightening, tighten until tight; when loosening, loosen once. The answer is yes. Desheng's disposable virus sampling pipe cover spin thread, and it is easy to screw.

Virus preservation solution: there are two kinds of virus preservation solution: inactivation and non inactivation.

Inactivation type: mainly the modified virus cracking preservation solution of nucleic acid extraction cracking solution, which can quickly and efficiently inactivate the virus protein cleavage of the sample to be tested, effectively prevent the operator from secondary infection, and also contain RNA enzyme inhibitor, which can protect the virus nucleic acid from degradation. And it can be kept at room temperature for a long time.

Non inactivation: it also retains the protein shell of the virus and the DNA or RNA of the virus nucleic acid, so that the integrity of the nucleic acid of the virus sample during the process of sending for examination can be guaranteed, and the original nature of the virus sample is largely maintained. It is a kind of culture virus transport medium. It is important to note that the preservation of the virus samples for a long time needs to be kept strictly low temperature.

We Desheng is through layer by layer inspection and quality control, whether it is in sampling swabs or in virus storage tubes and virus storage solutions. At the same time, we also have professional customer service to track and answer various questions.
