Abstract
An antigenic determinant that occurs on all IgA proteins except on IgA2 proteins of the A2m2 allotype is described. The determinant is an isoallotype, being an isotype of IgA1 and at the same time an allotype of IgA2 proteins. It is proposed that the symbol nA2m2 be used for the new determinant, where n stands for isoallotype (formerly nonmarker) and A2m2 refers to the allotype to which it is antithetically related.
摘要
本文描述了一种抗原决定簇，它存在于除A2m2同种异型的IgA2蛋白之外的所有IgA蛋白上。该决定簇是一种同种异型，既是IgA1的同种型，同时又是IgA2蛋白的同种异型。建议使用符号nA2m2来表示这种新的决定簇，其中n代表同种异型（以前称为非标记），A2m2指与之相对应的同种异型。
