Fig. 5. Reappearance of the MHC class I complexes at the cell surface after treatment with low pH buffer: effect of TNF-α. / Aliquots of cells cultured in standard medium with (▪) or without (○) TNF-α were treated with low pH buffer, washed, and cultured at 37°C for the indicated periods of time. For each time point, the amount of MHC class I complexes at the cell surface was calculated as percentage relative to the level of MHC class I detected before treatment with low pH buffer. (A) Reappearance of the MHC class I complexes at the cell surface of the 397 melanoma cell line. Mean ± SD of 3 experiments is shown in the figure. (B) Reappearance of the MHC class I complexes at the cell surface of the BL melanoma cell line. Results of 1 representative out of 2 performed experiments are shown.
