过去已经发表了几个可获得高度纯化的多角体病毒悬浮物的方法,但其中大都只能用于少量提取,并且这些方法都是相当细致难行的。因此,就感到有必要提出一个方法,对半扩大的、严重污染了的多角体病毒制备品进行纯化。在这个报告,应用了多角体病毒的比重为1.268,作为所提出的纯化方法的助力。 Several methods for obtaining highly purified polyhedrosis virus suspensions have been published in the past, but most of them are only used for small amounts of extraction, and these methods are rather cumbersome. Therefore, there is a feeling of need to propose a method for the purification of semi-expanded and heavily contaminated polyhedrosis virus preparations. In this report, the polyhedrosis virus was used at a specific gravity of 1.268 as a boost to the proposed purification method.
