摘要: 纯化的多角体碱解释放多角体蛋白,经等电点沉淀和柱层析对多角体蛋白进行分离纯化,结合SDS-PAGE、免疫双向扩散、免疫电镜等方法,证明棉铃虫核型多角体病毒(HaNPV)的多角体蛋白以聚集体形式存在。用ELISA法检测包涵体蛋白之间的血清学关系,结果表明,与黄地老虎颗粒体病毒(AsGV)和粘虫颗粒体病毒(PsGV)颗粒体蛋白相比较,HaNPV多角体蛋白与葡萄天蛾核型多角体病毒(ArNPV)和黄地老虎核型多角体病毒(AsNPV)多角体蛋白之间的血清学关系更为密切。

Abstract: Analysis of HaNPV polyhedrin purified with gel filtration chromatography, by SDS-PAGE, immunodiffusion and immunoelectron microscopy suggested that the polyhedrin exist in the form of aggregates. Enzyme linked immunosorbent assay (ELISA) revealed that the polyhedrin was more closer in serology to other two polyhedrins from ArNPV and AsNPV than two granulins from AsGV and PsGV, respectively.
