DNA疫苗在大流行应用中具有快速部署的巨大潜力,其中新抗原被“插入”到经验证的载体中,并在经验证的发酵-纯化过程中快速产生。对于这种应用,载体和发酵过程必须与各种不同的抗原基因一起发挥作用。然而,许多抗原基因在标准发酵过程中是不可预测的“毒性”或低产量的。我们报告细胞库和发酵工艺单元操作的创新,减少质粒介导的代谢负担,使以前已知的有毒流感血凝素抗原基因的成功生产。与现有的高拷贝载体(如pVAX 1和gWIZ)相比,这些方法与载体骨架修饰相结合,使发酵生产率加倍,导致高质粒产率(高达2220 mg/L,总干细胞重量的5%),即使使用先前鉴定的有毒或不良生产插入物。
DNA vaccines have tremendous potential for rapid deployment in pandemic applications, wherein a new antigen is ‘plugged’ into a validated vector, and rapidly produced in a validated, fermentation - purification process. For this application, it is essential that the vector and fermentation process function with a variety of different antigen genes. However, many antigen genes are unpredictably ‘toxic’ or otherwise low yielding in standard fermentation processes. We report cell bank and fermentation process unit operation innovations that reduce plasmid-mediated metabolic burden, enabling successful production of previously known toxic influenza hemagglutinin antigen genes. These processes, combined with vector backbone modifications, doubled fermentation productivity compared to existing high copy vectors, such as pVAX1 and gWIZ, resulting in high plasmid yields (up to 2220 mg/L, 5% of total dry cell weight) even with previously identified toxic or poor producing inserts.
