Abstract
The blood group B specificity of Escherichia coli O(86) antigen, a B specific oligosaccharide fraction from it, and the B activity of a preparation of an "infectious mononucleosis receptor" from cattle erythrocytes are destroyed by alpha-galactosidase from the coffee bean, as demonstrated for the E. coli antigen by three methods. Blood group H(O) activity appears simultaneously. Galactose is the only hexose released from all three substances.
摘要
大肠杆菌O(86)抗原的B血型特异性、从中提取的一种B特异性寡糖组分以及牛红细胞“传染性单核细胞增多症受体”制剂的B活性，经咖啡豆中的α-半乳糖苷酶作用后被破坏，这在大肠杆菌抗原上通过三种方法得到了证实。血型H(O)活性同时出现。半乳糖是从所有这三种物质中释放出的唯一己糖。
