Immunochemical properties of glycopeptides III and IV obtained from haptoglobin (Hp) types 1-1, 2-1, and 2-2, by trypsin digestion were studied by double immunodiffusion test, quantitative precipitation and crossed immunoelectrophoresis with antisera directed against Hp 1-1, Hp 2-1, and Hp 2-2, respectively. Trypsin digestion resulted in an exposition in the glycopeptide IV 1-1 of the antigenic determinant characteristic of Hp 1-1, which had been hidden inside the molecule of the native Hp 1-1. On the contrary, it was not possible to find an antigenic determinant characteristic of the product of alpha 2 gene.
通过胰蛋白酶消化从1-1型、2-1型和2-2型触珠蛋白（Hp）获得的糖肽III和IV的免疫化学性质，分别用针对Hp 1-1、Hp 2-1和Hp 2-2的抗血清，通过双向免疫扩散试验、定量沉淀和交叉免疫电泳进行了研究。胰蛋白酶消化导致隐藏在天然Hp 1-1分子内部的、具有Hp 1-1特征的抗原决定簇在糖肽IV 1-1中暴露出来。相反，未能找到α2基因产物特征性的抗原决定簇。
