Cross-linking of effector T cells to target cancer cells augments their tumor lytic activities. Here we describe a new method of conjugating lymphokine-activated killer (LAK) cells with cancer-specific monoclonal antibody. The LAK cells were biotinylated, treated with avidin, and conjugated with biotinylated monoclonal antibody. These monoclonal antibody-conjugated LAK cells showed specifically enhanced killing activities against anti-tumor antibody-reactive cancer cells, and cold target cells specifically inhibited their activities.
效应T细胞与靶癌细胞的交联增强了它们的肿瘤溶解活性。在此,我们描述了一种将淋巴因子激活的杀伤(LAK)细胞与癌症特异性单克隆抗体偶联的新方法。将LAK细胞进行生物素化处理,用抗生物素蛋白处理,然后与生物素化的单克隆抗体偶联。这些单克隆抗体偶联的LAK细胞对抗肿瘤抗体反应性癌细胞的杀伤活性有特异性增强,冷靶细胞可特异性抑制其活性。
