Western blot - Anti-HIF-1 alpha antibody [EPR16897] (AB179483)

Lanes 1 - 6 : Merged signal (red and green). Green - ab179483 observed at 105 kDa. Red - loading control, ab24834, observed at 50 kDa.

ab179483 was shown to specifically react with HIF-1 alpha in wild-type HAP1 treated DMOG (0.5mM 18hr) cells as signal was lost in HAP1 knockout treated DMOG (0.5 mM 18hr) knockout cells. Wild-type and HAP1 knockout samples were subjected to SDS-PAGE. ab179483 and ab24834 (Mouse anti-Histone H3 loading control) were incubated overnight at 4°C at 1/1000 dilution and 1/10000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye^® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye^® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
