A survey of human sera from healthy individuals revealed the presence of naturally occurring antibodies that react in radioimmunoprecipitation assays with proteins of mammalian type-C viruses. Of 39 sera tested, 100% showed reactivity against baboon endogenous virus, whereas only 49% showed reactivity against simian sarcoma-associated virus. Polyacrylamide gel electrophoresis of immune precipitates revealed one to three bands that comigrate with the virus structural proteins. There were low, but detectable, levels of antibody to the major internal protein of murine leukemia virus, but no activity against the structural proteins of avian sarcoma virus.
对健康个体的人血清进行的一项调查显示，存在天然产生的抗体，这些抗体在放射免疫沉淀试验中与哺乳动物C型病毒的蛋白质发生反应。在检测的39份血清中，100%显示出对狒狒内源性病毒的反应性，而只有49%显示出对猿猴肉瘤相关病毒的反应性。免疫沉淀物的聚丙烯酰胺凝胶电泳显示出一到三条与病毒结构蛋白迁移率相同的条带。存在低水平但可检测到的针对鼠白血病病毒主要内部蛋白的抗体，但对禽肉瘤病毒的结构蛋白没有活性。
