20L / Barrel Virus Transport Media And How To Collect VTM Tube Correctly

Introduction of Virus Transport Media and how to collect VTM tube correctly,20L/barrel

COVID-19 is sweeping the world. Every country in the world needs a large number of nucleic acid tests every day. However, nucleic acid examination requires the confirmation of the results in a specific environment. The virus preservative produced by Desheng is suitable for the collection, preservation and transportation of common virus samples such as New Coronavirus, influenza virus and hand foot mouth virus. It is a liquid for sampling the swab virus samples in the sampling tube, a liquid to protect the detected substances of the virus, and can collect throat swabs, nasal swabs or tissue samples of specific parts. The stored samples can be used for subsequent clinical experiments such as nucleic acid extraction or purification. It is usually divided into two types, one is non inactivated type, which can protect the protein and nucleic acid of the virus, and the other is inactivated type, which usually contains the cleavage salt of inactivated virus to cleave the protein and protect the nucleic acid.

Virus sample collection method:

First, nasal swab: slowly insert a plastic rod swab with a polypropylene fiber head into the nasopalatine part of the nasal canal, stay for a while, and then rotate it gently to take it out. Then take another plastic rod swab with polypropylene fiber head and collect the other nostril in the same way. Immerse the two collected swabs into the same tube containing 30% of the sampling solution, discard the tail, and tighten the tube cover.

Second, pharyngeal swab: wipe bilateral pharyngeal tonsils and posterior pharyngeal wall with two plastic rod swabs with polypropylene fiber head, immerse the swab head into a tube containing 3ml Virus Transport Media, discard the tail, and tighten the tube cover.

Third, nasopharynx extract or respiratory tract extract: use the collector connected to the negative pressure pump to extract mucus from the nasopharynx or respiratory tract secretion from the trachea. Insert the collector head into the nasal cavity or trachea, connect the negative pressure, rotate the collector head and exit slowly, collect the extracted mucus, and flush the collector with 3ml sampling solution once.

Swab is a common method for sampling virus samples. Combined with PCR, it can be used for rapid detection of viral diseases. However, not every sample collection place can be tested by PCR, so it is necessary to transport the collected virus swab samples.

The Virus Transport Media produced by Desheng has independent research and development, accurate detection, preferential price, high quality assurance, factory delivery and batch export. Welcome to consult.
