Digestion of bovine erythrocytes (BE) with trypsin (Tr) or chymotrypsin (CTr) revealed 'Tr and CTr specific' receptors respectively. These receptors reacted with all the isologous, including the autologous, sera. The titres of agglutinability varied for the Tr-digested BE from 1:2 to 1:64 and from zero to 1:128 for the CTr-digested BE. However, the variation between the members of monozygous twin pairs (MZ) in no case exceeded +/- 2 score units, the error limits. Agglutination of the CTr-digested BE gave with the PHA lectin very similar, (r = 0.964) results to that which was obtained with the isologous sera. The titre of agglutinins showed concordance in all the sera of MZ pairs when tested against the neuraminidase-digested human erythrocytes and the Tr or CTr-digested BE. Their variance due to differences varied between MZ pairs from 60.4 to 74.3%.
用胰蛋白酶（Tr）或胰凝乳蛋白酶（CTr）消化牛红细胞（BE）分别揭示了“Tr特异性”和“CTr特异性”受体。这些受体与所有同源血清反应，包括自体血清。经Tr消化的BE的凝集滴度从1:2到1:64不等，经CTr消化的BE的凝集滴度从零到1:128不等。然而，同卵双胞胎（MZ）成员之间的差异在任何情况下都未超过±2个评分单位，即误差限度。用PHA凝集素对经CTr消化的BE进行凝集反应，其结果与用同源血清获得的结果非常相似（r = 0.964）。当针对神经氨酸酶消化的人红细胞以及经Tr或CTr消化的BE进行测试时，MZ对所有血清中的凝集素滴度显示出一致性。由于差异导致的它们之间的方差在MZ对之间从60.4%到74.3%不等。
