Virus Transport Media-Swab —Special raw material for nucleic acid detection
Because of the New Coronary Pneumonia epidemic, the national economy has been deeply affected. In order to restore the normal operation of the national economy, all regions have to make preparations to resume work and resume school. However, in the absence of confirmed cases for many days, Undetected asymptomatic infections are becoming more active. Nucleic acid testing is the main method for detecting the number of diagnosed patients, and the virus transport media is a special raw material for nucleic acid testing.
Swab is a commonly used method for virus sample collection. It can be used for rapid detection of viral diseases in combination with PCR. Most sample collection sites cannot be PCR tested, so the collected viral swab samples need to be transported.
Specimen collection method:
1.Pharyngeal swab: wipe the bilateral pharyngeal tonsils and the posterior pharyngeal wall with two polypropylene fiber swabs at the same time, and immerse the swab head in a solution containing 3ml of virus (isotonic saline solution, tissue culture , Liquid or phosphate buffer solution can also be used)), discard the tail and tighten the cap.
2. Nasal swab: Insert a polypropylene fiber-tipped plastic rod swab gently into the nasal palate in the nasal canal, and after a while, slowly turn to exit. Take another plastic swab with polypropylene fiber tip and collect the other nostril in the same way. The above two swabs were immersed in the same tube containing 3 ml of sampling solution, the tail was discarded, and the tube cap was tightened.
3.Nasopharyngeal extracts or respiratory tract extracts: use a collector connected to a negative pressure pump to extract mucus from the nasopharynx or airway secretions from the trachea. Insert the head of the collector into the nasal cavity or trachea, turn on the negative pressure, rotate the head of the collector and slowly exit, collect the extracted mucus, and rinse the collector once with 3ml of sampling liquid.
Virus transport media is suitable for the collection, storage and transportation of common virus samples such as new coronavirus, influenza virus, hand, foot and mouth virus. It can collect pharyngeal swabs, nasal swabs or tissue samples of specific parts, and the stored samples can be used for subsequent clinical experiments such as nucleic acid extraction or purification. The virus preservation solution developed by Desheng is divided into activation and inactivation. It can also provide pharyngeal swabs and nasal swabs for specimen collection. If necessary, please call for detailed consultation.
