The anti-DNP antibodies produced by primary and secondary splenic foci were analyzed for heavy chain class by a radioimmunoassay, using iodinated, purified goat antimouse micro-chain antibody and goat antimouse gamma1 chain antibody. The frequency of primary and secondary foci producing both IgM and IgG1 anti-DNP antibody (16% and 14%, respectively) was considerably higher than that which would be predicted by a random distribution. It would thus appear that IgM and IgG1 antibody can be made by the clonal progeny of a single precursor cell.
通过放射免疫分析法,使用碘化的纯化山羊抗小鼠μ链抗体和山羊抗小鼠γ1链抗体,对初级和次级脾灶产生的抗二硝基苯酚(DNP)抗体的重链类别进行了分析。产生IgM和IgG1抗DNP抗体的初级和次级脾灶的频率(分别为16%和14%)明显高于随机分布所预测的频率。因此,似乎IgM和IgG1抗体可由单个前体细胞的克隆后代产生。
