Due to the impact of the epidemic and the Spring Festival approaching, nucleic acid testing has become a pass for our normal travel. This has also led to a sharp increase in the market demand for virus sampling tubes and virus preservation solutions. With demand, there will naturally be supply, which leads to the emergence of a lot of business information. The variety and quality of the products are also uneven. How to choose a regular and guaranteed virus sampling tube and virus transport media This is the voice of every buyer.

Disposable virus sampling tube: (sampling swab + virus preservation tube + virus preservation solution)
1. Sampling swab: The sampling swab directly contacts the sampling site, 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 (man-made fiber). Calcium alginate sponge or wooden stick swabs (including bamboo sticks) cannot be used, and the material of the swab head cannot be cotton. Because the fiber of cotton has a strong adsorption of protein, it is not easy to be eluted into the subsequent preservation solution; and the broken wooden stick or bamboo stick containing calcium alginate and wooden components will also adsorb protein after being soaked in the preservation solution, and even will It has an inhibitory effect on the subsequent PCR reaction.
2. Virus storage tube: It is mainly to prevent leakage. Can you find such a storage tube When tightening, it is tightened until it is tightened; when unscrewing, it is loosened as soon as it is twisted. The answer is yes. Desheng's disposable virus sampling tube cap has a spin thread, which can be screwed tightly without hindrance.

3. virus transport media: There are two types of virus preservation solution: inactivated and non-inactivated.
Inactivated type: It is mainly a virus lysis type preservation solution improved by nucleic acid extraction lysis solution, which can quickly and efficiently lyse and inactivate the virus protein in the sample to be tested, which can effectively prevent the operator from secondary infection, and also contains RNase inhibitors. , can protect the viral nucleic acid from being degraded. And it can be stored at room temperature for a relatively long time.
Non-inactivation: It also retains the protein coat of the virus and the viral nucleic acid DNA or RNA, so as to ensure the integrity of the nucleic acid of the virus sample during the inspection process, and maintain the originality of the virus sample to a large extent. For cultured virus transport media, it should be noted that long-term storage after sampling requires strict low-temperature storage.
Whether we are sampling swabs or virus storage tubes and virus transport media, Desheng has gone through layers of checks and quality control. At the same time, for after-sales service, we also have professional customer service to track and answer various questions.
