Abstract
利用新型一次性培养袋在5~10L激流灌注式生物反应器中培养3种贴壁和3种悬浮细胞,通过在线控制培养温度、pH值和溶氧等工艺参数,监测并分析培养过程中细胞密度、活率、糖耗等的变化情况.结果表明,贴壁培养细胞MDCK,VERO和DF-1培养6d后消化计数,密度分别达4.8×106,1.0×107和1.5×107mL-1,细胞状态良好,活率在90%以上.悬浮细胞CHO,BHK-21和Sf9经无血清悬浮驯化后,经种子链扩增,在激流式反应器中悬浮培养的初始接种密度分别为2.0×106,2.1×106和2.15×106mL-1时,培养一段时间后其最高培养密度分别可达2.0×107,2.1×107和1.8×107mL-1,维持培养时间分别为13,12和10d
