This invention provides a process for the continuous alkaline lysis of a bacterial suspension in order to harvest pDNA. It further provides for optional additional purification steps, including lysate filtration, anion exchange chromatography, triplex affinity chromatography, and hydrophobic interaction chromatography. These optional purification steps can be combined with the continuous lysis in order to produce a highly purified pDNA product substantially free of gDNA, RNA, protein, endotoxin, and other contaminants.
本发明提供了一种连续碱性裂解细菌悬浮液以收获 pDNA 的工艺。它进一步提供了可选的附加纯化步骤,包括裂解液过滤、阴离子交换色谱、三重亲和层析和疏水相互作用层析。这些可选的纯化步骤可与连续裂解结合使用,以生产出高度纯化的 pDNA 产品,其中基本上不含 gDNA、RNA、蛋白质、内毒素和其他污染物。
