| 摘要 |
The present invention describes methods and processes for the production of proteins by animal cell or mammalian cell culture. In one aspect, the methods comprise the growth of cells in a growth factor/protein/peptide free medium. In another aspect, the methods comprise the addition of growth factors during the production phase. The methods sustain a high viability of the cultured cells, and can yield an increased end titer of protein product, and a high quality of protein product. |
