ADCC activity against RPMI 8226 cells by spleen cells of SCID mice. In this experiment, mice were not treated with rabbit antiasialo GM1 antiserum. 51Cr-labeled RPMI 8226 cells were incubated with spleen cells in the presence of 1 μg/mL control IgG (○), anti-HM1.24 F(ab′)2 (▪), or anti-HM1.24 IgG (•). Data represent the mean ± SD of triplicates. Results are shown for a single experiment, but have been confirmed in two further experiments.
