| 摘要 |
The invention relates to a method for producing a serum-containing culture medium for cells, especially human and animal cells. The culture medium and/or the serum is/are filtered by means of an ultra-filtration membrane. In a preferred embodiment, the degrading rate of the filtration membrane is detected by means of viruses of the family leviviridae or comparably small bacteriophages. The thus obtained culture medium is used for cultivating natural and recombinant cells and hyridoma cells and for producing diagnostic control serums, especially for producing pharmaceutical and/or diagnostic preparations. |
