Due to a sudden new coronary pneumonia in early 2020, Virus Transport Media appeared in the public eye. But what exactly does it do, I think most people still don't know. Let's first talk about the role of inactivated Virus Transport Media.
What is inactivation? Inactivation refers to the use of physical or chemical means to kill viruses, bacteria, etc., but does not damage the useful antigens in their bodies.
Inactivated virus: The high-level structure of the virus protein is destroyed, and the protein no longer has physiological activity, so it loses the ability to infect, cause disease and reproduce, but the conventional inactivation does not affect the primary structure of the virus protein, which means the sequence of the virus protein no change.
Inactivated Virus Transport Media: It is a colorless and transparent liquid, suitable for various types of viruses, new coronaviruses, various influenza, avian flu, hand, foot and mouth urticaria and other viruses. A high concentration of guanidine salt is used to achieve rapid inactivation and preservation of respiratory pathogens, so that the sample loses infectivity. The inactivated samples can be used with the corresponding new coronavirus RNA extraction kit, M32/M96 nucleic acid extractor, etc. to quickly extract viral nucleic acid, and the new coronavirus PCR detection kit can be used to achieve rapid detection without specific sensitivity. influences. Applicable kit methods: fluorescent PCR method, combined probe anchoring polymerization sequencing method, constant temperature amplification chip method, magnetic particle chemiluminescence method, colloidal gold method.
It has the following advantages:
1. Efficiently inactivate viruses to avoid cross-infection caused by centralized sampling
2. Inactivate the virus, reduce the difficulty of storage and transportation
3. The sample loses its infectivity and protects the testing personnel
4. Widely used in PCR laboratory
The product developed and produced by Desheng is suitable for the collection, preservation and transportation of common virus samples such as new coronavirus, influenza virus, hand, foot and mouth virus. Pharyngeal swabs, nasal swabs or tissue samples of specific parts can be collected, and the stored samples can be used for subsequent clinical experiments such as nucleic acid extraction or purification.
