研究了阴离子交换色谱法作为浓缩和纯化细菌病毒的替代方法(并比较了参数)。用Convective Interactive Media®整料进行色谱法,具有三种不同的体积和两种基质化学。11个形态不同的细菌进行了测试,感染五种不同的细菌物种。对于每种测试的样品,优化了方案,包括柱化学、上样、缓冲液和洗脱条件的选择。柱上的吸附容量和回收率在100 - 200之间变化很大。我们的结论是,阴离子交换色谱与整料是一个有效的替代更传统的氯化铯纯化,具有放大的优势,但它需要更广泛的优化。
The use of anion-exchange chromatography was investigated (and parameters compared) as an alternative method to concentrate and purify bacterial viruses. Chromatography was performed with Convective Interactive Media® monoliths, with three different volumes and two matrix chemistries. Eleven morphologically distinct phages were tested, infecting five different bacterial species. For each of the phages tested, a protocol was optimized, including the choice of column chemistry, loading, buffer and elution conditions. The capacity and recovery of the phages on the columns varied considerably between phages. We conclude that anion-exchange chromatography with monoliths is a valid alternative to the more traditional CsCl purification, has upscaling advantages, but it requires more extensive optimization.
