Application of baby hamster kidney(BHK)-21 cell serum-free suspension culture technology in foot-and-mouth disease vaccine production
ActiveCN102178946AShort cycleIncrease productionMicroorganism based processesAntiviralsSerum igeSerum free
The invention discloses application of a baby hamster kidney(BHK)-21 cell serum-free suspension culture technology in foot-and-mouth disease vaccine production, which comprises the following steps of: 1) performing cell recovery; 2) performing reactor culture and cell amplification culture; and 3) inoculating foot-and-mouth disease virus seed venom and collecting the venom. A process for producing foot-and-mouth disease inactivated vaccines by culturing the BHK-21 cells through serum-free suspension culture and a step-by-step cell amplification method make the production period f the foot-and-mouth disease vaccines shortened and yield increased, and ensure stable quality and obvious benefit. The production process reduces the using amount of a culture medium, and the amount of the collected virus liquid is the culture medium consumption amount, while the culture medium consumption amount in a roller bottle production process is 2 times higher than the amount of the collected virus liquid, and bovine serum which is about 5 percent of the culture medium amount is needed.
