The preservation solutions of non – inactivated virus sampling tubes mainly contain the following components:
- Buffering agents
- Hanks’ buffer solution: This is a commonly – used buffer solution that can create a neutral environment, helping to maintain the stability of the pH value of the preservation solution and providing a suitable living environment for viruses, increasing the survival time and infection stability of viruses. For example, during the transportation and storage after sampling, Hanks’ buffer solution can prevent large changes in the pH value of the preservation solution and avoid affecting the activity of viruses due to inappropriate acidity or alkalinity.
- Nutrients
- Proteins: Such as bovine serum albumin (BSA), which can form a protective film on the protein shell of viruses, making them less likely to decompose, ensuring the integrity of viruses, and providing certain nutritional support for viruses to ensure that viruses can maintain good activity in an in – vitro environment.
- Glucose: It provides an energy source for viruses, supports the basic metabolic activities of viruses, and helps to maintain the activity of viruses.
- Antibiotics: Usually, multiple antibiotics are used in combination, which have antibacterial and antifungal effects, can inhibit the growth of bacteria and fungi, avoid microbial contamination of samples during collection and storage, and thus ensure the purity and activity of virus samples.
- Cryoprotectants: They can protect viruses from damage in a low – temperature environment, help to extend the preservation time of viruses, and facilitate long – distance transportation and long – term storage of samples.
- Phenol red indicator: The phenol red solution changes color due to changes in the pH of the solution and can be used as an indicating component to identify whether the preservation solution has deteriorated.
