Tolerance to SRBC has been induced in adult mice by the aid of cyclophosphamide, and the duration of the tolerant state has been tested by a second injection of antigen at different times thereafter. As evidenced by 19S and 7S PFC 4 days after challenge, tolerance in this model is of relatively short duration and leads spontaneously to a memory state.
借助环磷酰胺已在成年小鼠中诱导出对绵羊红细胞（SRBC）的耐受性，并且通过在之后不同时间再次注射抗原来测试耐受状态的持续时间。如攻击后4天19S和7S空斑形成细胞（PFC）所证明的，该模型中的耐受性持续时间相对较短，并会自发地转变为记忆状态。
