Immunocytochemistry/Immunofluorescent analysis of HIF-1-alpha (green) in HeLa cells either left untreated (left panel) or treated with 100uM Deferoxamine mesylate for ~16 hours (right panel). Formalin-fixed cells were permeabilized with 0.1% Triton X-100 in TBS for 15 minutes at room temperature and blocked with 0.3% BSA for 15 minutes at room temperature. Cells were probed with ab16066 at a dilution of 1/100 for at least 1 hour at room temperature and washed with PBS. Cells were then incubated with a DyLight 488-conjugated goat anti-mouse IgG secondary antibody at a dilution of 1/500 for 30 minutes at room temperature. F-actin (red) was stained with DyLight 594 Phalloidin and nuclei (blue) were stained with Hoechst dye.

Immunocytochemistry/Immunofluorescence analysis of U251 cells labeling HIF-1-alpha with ab16066. HIF-1-alpha (green), F-Actin staining with Phalloidin (red) and nuclei with DAPI (blue) is shown. Cells were grown on chamber slides and fixed with formaldehyde prior to staining. Cells were probed without (control - right) or with ab16066 (left) at a dilution of 1/20 over night at 4°C and incubated with a DyLight-488 conjugated secondary antibody. Images were taken at 60X magnification.

Immunocytochemistry/Immunofluorescence analysis of Human fibroblasts labeling HIF-1-alpha (green) with ab16066.Cells were fixed with paraformaldehyde, permeabilized with 0.3% Triton X-100 and blocked with 5% serum for 1 hour at 24°C. Samples were incubated with primary antibody (1/500 in 0.3% Triton X-100 + 1% BSA) for 1 hour 30 minutes at 24°C. An AlexaFluor®488-conjugated goat anti-mouse polyclonal IgG (1/2000) was used as the secondary antibody.See Abreview

Immunocytochemistry/Immunofluorescence labeling HIF-1-alpha with ab16066.

ab16066 staining HIF-1-alpha in Human small intestine (IBD) and tonsil tissue sections by Immunohistochemistry (IHC-P - paraformaldehyde-fixed, paraffin-embedded sections). Tissue was fixed with formaldehyde; antigen retrieval was by heat mediation with an EDTA buffer (pH 9.0). Samples were incubated with primary antibody (1/800 in diluent + background reducers) for 20 minutess at 25°C. An undiluted Goat polymer was used as the secondary antibody.See Abreview

Immunohistochemistry was performed on normal biopsies of deparaffinized Human tonsil tissue. To expose target proteins heat induced antigen retrieval was performed using 10mM sodium citrate (pH6.0) buffer microwaved for 8-15 minutes. Following antigen retrieval tissues were blocked in 3% BSA-PBS for 30 minutes at room temperature. Tissues were then probed at a dilution of 1/20 with ab16066 (left) or without primary antibody (negative control - right) overnight at 4°C in a humidified chamber. Tissues were washed extensively with PBST and endogenous peroxidase activity was quenched with a peroxidase suppressor. Detection was performed using a biotin-conjugated secondary antibody and SA-HRP followed by colorimetric detection using DAB. Tissues were counterstained with hematoxylin and prepped for mounting.
