Evidence has been advanced confirming earlier work that conglutinin reacts solely with a determinant exposed in fixed C′. The reactivity is not influenced by the decay of earlier components or the activity of later ones. Heterologous sources of C′ (rabbit and human) reacting with guinea-pig EAC′ give conglutinable intermediates. The stability of EAC′ for conglutination is much greater than for lysis. The study of decayed intermediates which still react with conglutinin suggests that the bulk of the C′ fixed has after some time no haemolytic function. Possible explanations of this phenomenon are discussed. The `long-term' functions of the bulk of the fixed C′ may therefore be associated with manifestations of complement activities other than haemolysis.
已有证据证实了早期的研究工作,即凝集素仅与固定补体C′中暴露的一个决定簇发生反应。这种反应性不受早期成分衰变或后期成分活性的影响。与豚鼠EAC′反应的异源补体C′(兔和人)可产生可被凝集的中间体。EAC′对凝集的稳定性远高于对溶解的稳定性。对仍与凝集素反应的衰变中间体的研究表明,大部分固定的C′在一段时间后不再具有溶血功能。本文讨论了这一现象的可能解释。因此,大部分固定C′的“长期”功能可能与除溶血以外的补体活性表现相关。
