The storage conditions of virus transport media vary depending on the specific situation

The storage conditions of virus transport media vary depending on the specific situation. The following are some common storage condition requirements:

Temperature aspect

• Room temperature range: Some virus transport media can be stored and transported at room temperature (5-25°C) for a short period of time. For example, a one-time delivery medium product can be stable at room temperature for up to 14 days.
• Refrigeration conditions: A commonly used refrigeration storage temperature is 2-8°C. If the collected virus samples cannot be detected in time, specimens to be detected within 24 hours can be stored at 4°C.
• Freezing conditions: For virus samples that need to be stored for a long time, -70°C or lower is an ideal freezing storage temperature; if there is no -70°C storage condition, they can be temporarily stored in a -20°C refrigerator, but the effect may not be as good as -70°C.

Other aspects

• Packaging integrity: Virus transport media need to be stored in a well-sealed container to prevent leakage and the entry of external substances, avoiding sample contamination and the culture medium itself.
• A light-shielding environment: Virus transport media should be placed in a light-shielding place as much as possible to prevent certain components in the medium (such as possible nutrients, protective agents, etc.) from degrading or deteriorating due to light.
• Avoid vibration and shaking: During the storage process, vigorous vibration and shaking of the culture medium should be avoided to prevent damage to the structure and activity of the virus.
