• Figure 1 - Wide field images of MHCI staining upon U0126 treatment. HeLa cells were pre-treated for 1 hour with (A) U0126 (50 μM) or (B) DMSO, then incubated with anti-MHCI for 4 hours in the continued presence of the drug. Cells were fixed and processed for confocal microscopy. Images represent fields chosen at random from two independent experiments.
