Intact particles of Friend leukemia virus derived from infectious mouse serum absorb only trace amounts of cytotoxic anti-FMR antibodies, but physical disruption of the virions by freezing and thawing, by ether extraction or by detergent treatment releases large amounts of FMR antigenic activity. Thus this antigen, previously considered to occur mainly as a neo-antigen on the surfaces of virus-infected cells and as a soluble substance in the serum of infected mice, may be primarily a virion component.
源自感染性小鼠血清的弗瑞德白血病病毒完整颗粒仅吸附微量的细胞毒性抗FMR抗体,但通过冻融、乙醚提取或去污剂处理对病毒粒子进行物理破坏会释放大量FMR抗原活性。因此,这种抗原以前被认为主要作为病毒感染细胞表面的新抗原以及感染小鼠血清中的可溶性物质存在,现在可能主要是病毒粒子的一种成分。
