摘要
对虾白斑综合征病毒(White spot syndrome virus,WSSV)是对虾养殖业的主要病原,自1992年以来一直严重影响对虾的产量和质量,造成巨大的经济损失.
The envelope proteins of White spot syndrome virus (WSSV) are very fragile and easy to be destroyed during purification. It was difficult to obtain a large quantity of intact virions by routine sucrose gradient centrifugation. After modifying the sucrose gradient by adding citrate sodium, we can obtain a large quantity of intact virions and nucleocapsids. This purified virions and nucleocapsids were subsequently used for analyzing viral structural proteins and DNA extraction. The result showed that this modified technique is very efficient for virus purification.
