Sheep antibodies, reactive with either the idiotypic or constant region antigenic determinants of the immunoglobulin light chain on guinea-pig L2C leukaemic cells, were separated into IgM and into the two subclasses of IgG, IgG1 and IgG2. Antibody of both IgG subclasses inhibited the migration of L2C cells along plastic surfaces; IgM was only weakly inhibitory. Antibody of class IgM and of subclass IgG1 mediated complement cytotoxicity against the L2C cells whereas only that of subclass IgG2 mediated K-cell cytotoxicity; the effector arms were rabbit complement and sheep peripheral leucocytes, respectively.
与豚鼠L2C白血病细胞免疫球蛋白轻链的独特型或恒定区抗原决定簇发生反应的绵羊抗体,被分离为IgM以及IgG的两个亚类,即IgG1和IgG2。两种IgG亚类的抗体均抑制L2C细胞沿塑料表面的迁移;IgM仅有微弱的抑制作用。IgM类和IgG1亚类的抗体介导针对L2C细胞的补体细胞毒性,而只有IgG2亚类的抗体介导K细胞细胞毒性;效应臂分别是兔补体和绵羊外周血白细胞。
