Abstract
Preferably, the cells are adherent cells such as Vero cells and the cells are cultivated as a continuous monolayer. The cells may be transfected with a gene construct which encodes a heterologous protein. Viruses of vaccines can be produced by culturing cells that have been infected with a virus.
Claims7
In a process for the cultivation and proliferation of Vero cells in a protein-free medium, wherein said cells are in contact with and cultured on a culture surface, the improvement comprising culturing said cells on a polyvinylformal and/or polyvinylbutyral culture surface.
