Two human sera having both complement-dependent and lymphocyte-dependent antibody activities (CDA, LDA) were applied to isoelectrofocusing columns. Maximum LDA activity for both sera was found focused at a higher pH than maximum CDA activity. The studies suggest that LDA molecules may exist without having complement-dependent activity.
将两种具有补体依赖性和淋巴细胞依赖性抗体活性（CDA、LDA）的人血清应用于等电聚焦柱。发现两种血清的最大LDA活性聚焦在比最大CDA活性更高的pH值处。研究表明，LDA分子可能在没有补体依赖性活性的情况下存在。
