Purified blood group A, B, and O substances from hog and human sources precipitate with Type XIV antipneumococcal horse serum and provide an explanation for the observation that Type XIV antibody agglutinates human erythrocytes of all four major blood groups. Individual preparations of A substance or O substance from either species vary in their capacity to precipitate Type XIV antibody although the hog A substances did not differ in potency toward anti-A. Similarly, no correlation between A activity and reactivity with Type XIV antibody could be found among the human A substances.
从猪和人源中纯化得到的血型A、B和O物质可与XIV型抗肺炎球菌马血清发生沉淀反应,这为XIV型抗体能凝集所有四种主要血型的人类红细胞这一现象提供了解释。尽管猪的A物质在抗A效力上并无差异,但来自任一物种的A物质或O物质的个别制剂在沉淀XIV型抗体的能力上有所不同。同样,在人类A物质中,未发现A活性与XIV型抗体反应性之间存在相关性。
