Western blot - Anti-HIF-1 alpha antibody [54/HIF-1a] - BSA and Azide free (AB279658)

False colour image of Western blot : Anti-HIF-1 alpha antibody [54/HIF-1a] staining at 1/2000 dilution, shown in green; Rabbit anti-alpha Tubulin antibody [EP1332Y] (ab52866) loading control staining at 1/20000 dilution, shown in red. In Western blot, ab279654 was shown to bind specifically to HIF-1 alpha. A band was observed at 110 kDa in treated wild-type HCT 116 cell lysates with no signal observed at this size in HIF1A knockout cell line ab255394 (knockout cell lysate ab263860). To generate this image, wild-type and HIF1A knockout HCT 116 cell lysates were analysed. First, samples were run on an SDS-PAGE gel then transferred onto a nitrocellulose membrane. Membranes were blocked in 3 % milk in TBS-0.1 % Tween^® 20 (TBS-T) before incubation with primary antibodies overnight at 4 °C. Blots were washed four times in TBS-T, incubated with secondary antibodies for 1 h at room temperature, washed again four times then imaged. Secondary antibodies used were Goat anti-Mouse IgG H&L (IRDye^® 800CW) preabsorbed (ab216772) and Goat anti-Rabbit IgG H&L (IRDye^® 680RD) preabsorbed (ab216777) at 1/20000 dilution.
