应用金黄色葡萄球菌(Staphglococcal)表面富含具有与人和某些动物IgG的Fc片段结合能力的蛋白质抗原成分——葡萄球菌A蛋白(Staphglococeal protein A简称SpA)的特性,以葡萄球菌为载体,用抗血清致敏后吸附病毒,用于电子显微镜中病毒检测。电镜下,当菌体充分吸附病毒后,即可形成具有花环样的特殊结构,故将本方法定名为SpA—G IEM(Staphglococcal protein A—Gayland Immune electron Miuoscopg)。 Staphglococcal surface is enriched with Staphglococeal protein A (SpA), a protein antigen component capable of binding with the Fc fragment of human and some animal IgGs, After antiserum sensitized, the virus was adsorbed and used to detect the virus in the electron microscope. Under the electron microscope, when the bacteria fully adsorbed the virus, it can form a special structure with a garland-like, so the method is named SpA-G IEM (Staphglococcal protein A-Gayland Immune electron Miuoscopg).
