Sampling methods for swabs.
1 . Disposable nasal swab: insert the swab head quietly into the nasal cavity for sampling and use other nasal swabs to collect other nasal samples in the same way so that the nasal swab head invades the cell preserving fluid and discard the tail.
2 . Disposable pharyngeal swab: collect pharyngeal samples with a pharyngeal swab, again making the pharyngeal swab head invade the cell preservation fluid and discarding the tail.
Precautions.
1 . Stop direct contact with the sampling solution.
2 . Stop sampling after wiping with the sampling solution.
3 . This product is a disposable product and cannot be reused.
4 . The product can be used within the expiration date, the expired product can not be used.
5 . Collection of virus specimens should be performed by experts in strict accordance with sampling procedures.
What is the virus preservation solution for virus swab sampling tube.
Virus sampling swabs are commonly used for viral sampling and can be used for rapid detection of viral diseases by combination with PCR. However, not all sample collection stations are available for nucleic acid testing and therefore need to ship collected viral swab samples and swab virus preservation solution will be shipped.
Viruses consist of a nucleic acid molecule and protein, or protein only, with a single tiny, simple structure, and common pandemics are usually RNA viruses such as influenza virus, HIV, and influenza A virus. The absence of a cellular structure makes it impossible to mimic the virus itself, allowing the genes to invade the host cell and mimic the new virus through the latter's mimicry system. After collecting a virus sample, the sample swab is placed in a preservation solution for preservation and delivery in order to maintain the activity of the virus sample and prolong the survival time of the virus in the sample.
Inactivated virus preservation solution
It includes Hanks' fluid root, gentamicin, fungal antibiotics, BSA (V ), cryoprotectant, biological buffer and amino acids. Multiple antibiotics are combined to have antibacterial and antifungal effects. Bovine serum albumin (BSA ) acts as a protein stabilizer, forming a protective film on the protein shell of the virus, which is not easily decomposed and can ensure the integrity of the virus. The neutral environment constructed by Hanks buffer helps to add the survival moment and infection stability of the virus.
