Abstract: | A serum free medium was developed, that could be used for the large scale propagation of various cell lines in bioreactors. The medium is based on a 1:1 mixture of Iscove's Modified Dulbecco's Medium and Ham's Medium F12, supplemented with transferrin, insulin and a BSA/oleic acid complex. Several myelomas, hybridomas derived from different myelomas and spleen cells, and other lymphoid and non-lymphoid cell lines were cultivated at growth rates comparable to those observed using serum-supplemented media. There was furthermore no reduction in the formation of products such as monoclonal antibodies or recombinant human interleukin-2.Abbreviations Ag8 Mouse myeloma cell line P3-X63-Ag8.653 - BME Basal Medium Eagle - BSA Bovine Serum Albumin - DMEM Dulbecco's Modified Eagle's Medium - EDTA Ethylenediaminete-traacetic Acid - e-PC Phosphatidyl choline from egg yolk - FCS Fetal Calf Serum - FGF Fibroblast Growth Factor - GHL Glycyl-histidyl-lysine - HDL High Density Lipoprotein - HPL Human Plasma Lipid - IF 1:1 mixture of IMDM and Ham's F12 - IMDM Iscove's Modified Dulbecco's medium - LDL Low Density Lipoprotein - NS1 Mouse myeloma cell line NSI-1-Ag4-1 - PBS Phosphate Buffered Saline - s-PC Phosphatidylcholine from soy beans - s-PE Phosphatidylethanolamine from soy beans - s-lecithin lecithin from soy beans |
