and HIF-1
Z. HEK 293 cells (left panel) and pHA-HIF-1
Z transfectant cells (right panel) were subjected to normoxia or 4 hours of hypoxia, and then incubated with rabbit anti-HIF-1
antibody and rabbit anti-HA antibody, respectively, followed by a FITC-conjugated goat anti-rabbit antibody. The corresponding transmission images are shown in the outer columns.
