China wholesale Dsc Portable Color Ultra Doppler - Vacuum Viral Transport Medium Tube – DSC

Product Description

Product Name: Vacuum Viral Transport Medium Tube

Item: Non-Inactivated Viral Transport Media Tube and Inactivated Viral Transport Media Tube

Preservation Solution Color: Inactivated Viral Transport Media Tube: Colorless and transparent ; Non-Inactivated Viral Transport Media Tube: Pink red.

Tube Size: 13*100 mm

Preservation Solution Volume: 2~3 ml

Non-inactivated preservation solution: It is mainly a virus-maintaining preservation solution that is improved based on the delivery medium. It can maintain the activity of the virus in vitro and the integrity of the antigen and nucleic acid. It contains Hanks liquid foundation, gentamicin, fungal antibiotics, BSA (V), cryoprotectant, biological buffer and amino acids, etc., and it is not easy to protect the virus protein shell Decomposition, to a large extent, maintain the originality of the virus sample. In addition to nucleic acid extraction and detection, this storage solution can also be used for virus culture, isolation, and antigen detection. However, long-term storage after sampling requires strict low temperature.

Inactivated preservation solution: mainly virus lysis preservation solution modified by nucleic acid extraction lysis solution. Containing a high concentration of guanidine salt during sampling can effectively inactivate the virus, which can effectively prevent the operator from secondary infection, but it also contains Rnase inhibitor, which can protect the virus nucleic acid from degradation, so that subsequent detection by NT-PCR . Moreover, it can be stored at room temperature for a relatively long time, saving the cost of virus sample storage and transportation.

Scope of application

This product is suitable for the collection, transportation and storage of virus sampling.

Instructions for use

1. Before sampling, mark the relevant sample information on the label of the sampling tube.

2. Use a sampling swab to sampling at the nasopharynx up to different sampling requirements.

3. Sampling methods are below:

a. Nasal swab: Gently insert the swab head into the nasal condyle of the nasal passage, stay for a while and then slowly turn it out, then immerse the swab head in the sampling solution, and discard the tail.

b. Pharyngeal swab: Wipe the bilateral pharyngeal tonsils and posterior pharyngel wall with the swab, immerse the swab head in the sampling solution, and discard the tail.

4. Quicky place the swab into the sampling tube.

5. Break the sampling swab above the sampling tube, and tighten the tube cap.

6. Freshly collected clinical specimens should be delivered to the laboratory within 2 hours at 2℃-8℃.
