Lipoprotein was isolated from tumour cells by sonication and ultracentrifugal flotation on KBr gradients. It contained H-2 antigen detectable by antibody binding and induced a primary or secondary cell-mediated cytotoxic response in vitro which was H-2 specific. In a syngeneic model only a secondary cell-mediated response was stimulated and no competitive inhibition of the effector step of cell-mediated lysis could be demonstrated. The implications of these findings are discussed.
通过超声处理和在KBr梯度上进行超速离心浮选从肿瘤细胞中分离出脂蛋白。它含有可通过抗体结合检测到的H-2抗原,并在体外诱导了H-2特异性的初次或二次细胞介导的细胞毒性反应。在同基因模型中,仅刺激了二次细胞介导的反应,并且未证明对细胞介导的裂解效应步骤有竞争性抑制作用。讨论了这些发现的意义。
