细菌病毒(噬菌体,或噬菌体)是琼脂覆盖层,用于分离新病毒,以及它们的量化和纯化。这里,提出了简单的优化方法,可提高基于琼脂覆盖的病毒宿主系统分离和培养的效率和吞吐量。琼脂覆盖层被流线型化以使步骤和材料最小化。对来自病毒菌落(噬斑)的病毒的连续纯化进行优化,以通过将连续重新划线的纯化与优化的琼脂覆盖方法相结合来消除步骤。最后,建议对病毒斑块进行有效的归档和储存。总之,这项工作提出了:•无管琼脂覆盖:步骤和材料较少的快速菌斑测定•单粒熔炼:病毒的快速无管连续纯化•存档菌斑:为以后保存病毒纯化。
A universal tool in the culture-based study of bacterial viruses (bacteriophages, or phages) is the agar overlay, which is used in the isolation of new viruses, and in their quantification and purification. Here, simple optimizations that increase efficiency and throughput in agar overlay based isolation and cultivation of virus-host systems are presented. The agar overlay is streamlined to minimize steps and materials. Serial purification of viruses from viral colonies (plaques) is optimized to eliminate steps by combining purification by serial re-streaking with the optimized agar overlay approach. Finally, recommendations are made for efficient archival and storage of virus plaques. In sum, this work presents: •Tube-free Agar Overlays: rapid plaque assays with fewer steps and materials•Molten Streaking for Singles: rapid tube-free serial purification of viruses•Archiving Plaques: saving virus purification for later.
