METHOD FOR PRODUCING tick-borne encephalitis-VIRUS (TBE VIRUS) antigen

摘要

The invention relates to a biomass for producing virus/virus antigen, which consists of cell aggregates of avian embryo cells having diameters of between 100 mu m and 1,000 mu m. The biomass according to the invention has a high metabolic activity in suspension in the culture medium and is infected with virus. It enables the large-scale production of pure virus/virus antigen and is particularly suitable for the production of TBE-virus/virus antigen.
