| 摘 要： | 研究以DMEM/F12(1:1 V/V)培养基为基础,添加不同添加剂优化一种适宜CHO DG44细胞生长的廉价培养基。以细胞密度和细胞活率为主要指标,对DMEM/F12(1:1 V/V)培养基进行了优化。通过正交试验和单因素试验筛选出了CHO DG44细胞生长的最佳培养基。正交试验结果表明添加8mg/L Insulin、10mg/L Transferrin、12mM Glutamine、9mg/L Ethanolamine、9mg/L Sodium selenite、0.5×Lipids、0.5×Vitamin,对细胞生长有较好促进作用,细胞密度从0.6×106 cells/mL上升到1.8×106 cells/mL。在此基础上添加2.5g/L Malt Peptone和2.5g/L YeastExtract可使细胞密度达到2.65×106 cells/mL,基本上达到商业培养基的培养效果,而成本降低了约60%。

| Abstract: | In order to get a cheap medium for CHO cells,different supplements were added to DMEM/F12 medium.It was found that cell density could be increased from 0.6×106 cells/mL to 1.8×106 cells/mL with addition of 8mg/L insulin,10mg/L transferrin,12mM glutamine,9mg/L ethanolamine,9mg/L sodium selenite,0.5 lipids and 0.5 vitamin.By supplying 2.5g/L malt peptone and 2.5g/L yeast extract,cell density reached 2.65×106 cells/mL,which was as same as cell density in commercial medium. |
