The virus delivery medium of the present invention comprises the following raw materials: Hank's balanced salt, hydrophilic colloid, serum albumin, disaccharides, amino acids, biological buffers and antibiotics. The tea product of the invention has the advantages of broad-spectrum antibacterial, slowing down virus degradation, maintaining virus activity and low preparation cost.

Description

technical field [0001] The invention relates to the field of culture fluid, in particular to a virus delivery medium and its preparation method and application. Background technique [0002] Changes in factors such as the environment may cause respiratory viruses to become active, posing a greater threat to human health. At present, people have realized the importance of etiological detection in the diagnosis and treatment of sudden infectious diseases, the demand for clinical virus detection is increasing, and the demand for virus delivery medium is also growing rapidly. [0003] Viruses are composed of nucleic acid molecules and proteins or only proteins. Viruses are small and simple in structure. The virus cannot replicate itself, but invades the host cell with genes, and replicates new viruses with the help of the host cell's replication system. Virus samples need to be collected before virus detection. After collection, the virus samples are stored and transported in ...
