An efficient capture step for human adenovirus type 5 from cell lysate was developed as an initial virus purification step from cell debris supernatant. Organosilane-based polymer particles were synthesized and experimental monomer screening allowed the selection of appropriate functionalities for the development of particles for virus binding. After elution, virus recoveries of 83 % were obtained with significant reduction of matrix proteins and residual host cell DNA. Therefore, the implemented capture strategy for adenovirus via polymer particles provides a scalable and reproducible approach to reduce time and cost during virus purification processes.
从细胞碎片上清液中作为初始病毒纯化步骤,开发了一种从细胞裂解物中有效捕获人 5 型腺病毒的方法。合成了基于有机硅烷的聚合物颗粒,通过实验单体筛选,为开发用于病毒结合的颗粒选择了合适的功能。洗脱后,病毒回收率达到 83%,基质蛋白和残留宿主细胞 DNA 显著减少。因此,通过聚合物颗粒实现的腺病毒捕获策略为减少病毒纯化过程中的时间和成本提供了一种可扩展且可重复的方法。
