Substitution of low-cost calf serum for fetal bovine serum was evaluated in Namalva cell production of human alpha-lymphoblastoid interferon [HuIFN-alpha(Ly)] in 50-liter fermentors. Namalva cell growth and IFN yields were greatly reduced and protein precipitate weight increased from calf serum-supplemented cell cultures. The overall reduction in IFN production was greater than threefold, making the substitution impractical.
在50升发酵罐中用人Namalva细胞生产人α-淋巴母细胞干扰素[HuIFN-α(Ly)]时,评估了用低成本小牛血清替代胎牛血清的效果。在添加小牛血清的细胞培养物中,Namalva细胞生长和干扰素产量大幅降低,蛋白质沉淀重量增加。干扰素产量总体降低超过三倍,使得这种替代不切实际。
