Recombinant Mouse Antibody (R24) is capable of binding to GD3 (cell-surface tumor antigen disialoganglioside), expressed in Chinese Hamster Ovary cells (CHO). R24 has been shown to prevent tumor development in animal models, as well as to display anti-tumor activity in human clinical trials.
Figure 1 R24 antibody is recycled to the plasma membrane and released into the culture medium.
(A) GD3-expressing CHO-K1 cells were incubated with R24 antibody for 45 min on ice. Afterwards, cells were allowed to internalize the antibody for 20 min at 37°C, and then the temperature was shifted again to 4°C. The cell surface was then stripped of any remaining antibody with acid wash (0 min). Cells were then incubated at 37°C to restore intracellular transport, and cells and culture medium were recovered at 15 and 60 min. The presence of R24 antibody in both samples was analyzed by western blot as indicated in Experimental procedures. (B) The relative contribution of bands in each condition was calculated using the computer software SCION IMAGE on the scanned film shown in (A). Ponceau S staining was used to normalize levels of proteins seeded in each lane. The band intensity for R24 antibody at 0 min (cellular fraction) was arbitrarily taken as 1. Results are representative of four independent experiments.

Figure 2 R24 antibody is internalized, recycled to the plasma membrane, and released into culture medium in SK-Mel 28 melanoma cells.
(A) SK-Mel 28 melanoma cells were metabolically labeled from [14C]galactose for 24 h. Lipid extracts were prepared, purified, chromatographed and visualized as indicated in Experimental procedures. The positions of cochromatographed glycolipid standards are indicated. The asterisk indicates the position of an unidentified lipid. (B) SK-Mel 28 melanoma cells were incubated with R24 for 45 min at 4°C. After washing of the cells, the temperature was shifted to 37°C to allow endocytosis of the complex GD3–R24, and cells were fixed at 15, 30 and 60 min. R24 antibody was detected by using anti-mouse IgG conjugated with Alexa488. Single confocal sections of 0.7 lm were taken parallel to the coverslip. (C) SK-Mel 28 melanoma cells were incubated with R24 antibody for 45 min on ice. Cells were allowed to internalize the antibody for 20 min at 37°C, and then the temperature was shifted again to 4°C. The cell surface was then stripped of any remaining antibody with acid wash (0 min). Then cells were incubated at 37°C to restore intracellular transport, and cells and culture medium were recovered at 30, 60 and 90 min. The presence of R24 antibody in both samples was analyzed by western blot as indicated in Experimental procedures. Scale bars: 20 μm.
