Western blot analysis of extracts from HeLa cells, treated with either 10 μM of MG132 (to accumulate hydroxylated HIF-1α) or 10 µM MG132 and 1 mM DMOG (to accumulate nonhyroxylated HIF-1α), using Hydroxy-HIF-1α (Pro564) (D43B5) XP ® Rabbit mAb (upper) or total HIF-1α Antibody #3716 (lower).
Confocal immunofluorescent analysis of HeLa cells, treated with either 10 μM MG132 (left) or 10 μM MG132 and 1 mM DMOG (right), using Hydroxy-HIF-1α (Pro564) (D43B5) XP ® Rabbit mAb (green). Actin filaments have been labeled using DY-554 phalloidin (red).
