Abstract

The invention discloses a serum-free medium suitable for large-scale single-cell suspension culture of young hamster kidney cells (BHK cells), including 21 kinds of amino acids, 11 kinds of inorganic salts, 12 kinds of vitamins, 1 kind of protein hydrolyzate, 2 kinds of Lipids, 2 buffer components and 6 additives. The BHK cell serum-free medium of the present invention produces biological products by single-cell suspension culture, which can not only avoid various disadvantages of serum culture, but also eliminate the problem of difficult scale-up of roller bottle adherent culture, thereby improving the production efficiency of BHK cell culture And reduce production costs, while ensuring product quality, has good application value and huge market prospects.

Description

technical field [0001] The invention relates to the field of cell culture medium, in particular to a serum-free culture medium suitable for large-scale single-cell suspension culture of young hamster kidney cells. Background technique [0002] Rabies is a natural foci or zoonotic acute infectious disease caused by rabies virus. It is widespread and has a high fatality rate. Strict management of dogs, dog immunization or extermination of dogs is a positive way to control human rabies. Useful ways. At present, there is no specific and effective treatment for the disease, and the fatality rate is almost 100%. Foot-and-mouth disease is an acute, febrile, highly contagious infectious disease of cloven-hoofed animals. Its virus mutation and epidemic spread are extremely fast, and it can infect more than 70 kinds of domestic and wild cloven-hoofed animals. It has a worldwide impact on animal husbandry and related industries. The industry has had a considerable impact. The World Or...
