Composition of Virus Preservation Solution and Its Inspection Principle1. The components of the preservation solution are: Hanks liquid base, gentamicin, fungal antibiotics, BSA (V), cryoprotectant, biological buffer, amino acid, etc. 2. The combination of multiple antibiotics has antibacterial and antifungal effects. 3. As a protein stabilizer, bovine serum albumin (BSA) can form a protective film on the protein shell of the virus, which makes it difficult to decompose and ensures the integrity of the virus. 4. The neutral environment constructed by Hanks buffer is helpful to increase the survival time and infection stability of the virus. 5 for clinical influenza, bird flu (such as H7N9), hand-foot-mouth disease, measles and other virus specimens and mycoplasma, ureaplasma, chlamydia and other specimens of collection and transportation.

 

Usage MethodSpecimen collection personnel should do personal protection according to relevant regulations.Swallow and nasal swabs should be collected 3 days before the onset of the disease. 1. In the safety cabinet, this product is sub-packed into a self-contained 5 mL screw cap plastic pipe (primary container) with rubber ring in the screw cap. Type B product is already in the spin-on centrifuge tube, this step can be skipped. 2. Collection of nasal swabs: Gently insert the swab into the nasal palate in the nasal passage, and slowly rotate and withdraw after stop for a minute. Wipe both nostrils with the same swab. Dip the cotton swab into the 3 mL cap centrifuge tube obtained in the previous step, discard the tail of the swab, and tighten the cap. 3. Collection of pharyngeal swabs: Wipe the bilateral pharyngeal tonsils and posterior pharyngeal wall with cotton swabs, immerse the cotton swabs into the centrifuge tube with 3 mL of this product obtained in the first step, discard the tail of the swab, and tighten the screw cap. 4. Directly write down the sample type, sampling time, serial number and patient's name with an oil marker on the primary container. (5) placing the sealed specimen into a plastic bag with suitable size for sealing; One specimen per bag. At the same time, the relevant information of the specimen will be filled in the specimen inspection form and sealed in a plastic bag together with the primary container. 6. Put the sealed bag containing specimens into the self-provided plastic container with screw cap and rubber ring (in the secondary container, tighten the cap and mark the relevant information on the container. More than 2 sealed specimens of the same patient can be placed in the same secondary container. The secondary container shall withstand a pressure of not less than 95 KPa, and shall be lined with substances with water absorption and buffering capacity. All containers must be printed with biohazard labels. 7. Place the secondary container in a special transport box (or vaccine transport box), put it into an ice bank, then fill it with soft material, seal it, and send it by a special person (2 persons), and do not mail it. It is better to use a special car. 8. If the collected specimens cannot be delivered within 24 hours, they should be kept below -70℃ as soon as possible. No -70℃ conditions need to be temporarily stored in a refrigerator at 4℃ for a short time, and contact the delivery specimen as soon as possible. Influenza viruses are unstable at 9-20℃ to-40℃, so long-term preservation is best performed below -70℃.
