为了确保安全性,监管机构建议从治疗和疫苗质粒DNA载体中消除抗生素抗性标记。在这里,我们描述了一种新的无障碍选择系统的开发和应用。载体掺入并表达150 bp RNA-OUT反义RNA。RNA-OUT抑制染色体整合的组成型表达的反向选择标记(sacB)的表达,从而允许在蔗糖上进行质粒选择。蔗糖选择性DNA疫苗载体结合了联合收割机无菌选择和高产发酵生产(>1 gm/L质粒DNA产量),同时改善了编码蛋白的体内表达并增加了对靶抗原的免疫应答。这些载体是DNA治疗或疫苗接种的更安全、更有效的替代品。
To ensure safety, regulatory agencies recommend elimination of antibiotic resistance markers from therapeutic and vaccine plasmid DNA vectors. Here, we describe the development and application of a novel antibiotic-free selection system. Vectors incorporate and express a 150 bp RNA-OUT antisense RNA. RNA-OUT represses expression of a chromosomally integrated constitutively expressed counter-selectable marker (sacB), allowing plasmid selection on sucrose. Sucrose selectable DNA vaccine vectors combine antibiotic-free selection with highly productive fermentation manufacturing (>1 gm/L plasmid DNA yields), while improving in vivo expression of encoded proteins and increasing immune responses to target antigens. These vectors are safer, more potent, alternatives for DNA therapy or vaccination.
