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 a HIF-1 alpha monoclonal antibody (Product # MA1-516) at a dilution of 1:100 for at least 1 hour at room temperature, washed with PBS, and incubated with a DyLight 488-conjugated goat anti-mouse IgG secondary antibody (Product # 35502) at a dilution of 1:500 for 30 minutes at room temperature. F-actin (red) was stained with DyLight 594 Phalloidin (Product # 21836) and nuclei (blue) were stained with Hoechst 33342 dye (Product # 62249). Images were taken on a Thermo Scientific ArrayScan Instrument at 20X magnification.

MA1-516 detects hypoxia-inducible factor 1 alpha (HIF-1 alpha) from human, non-human primate, bovine, mouse and porcine cells. This antibody does not cross-react with ARNT or the related HIF-2 alpha.
MA1-516 has been successfully used in Western blot, immunofluorescence, immunoprecipitation, immunocytochemistry, and gel shift procedures. By Western blot, this antibody detects an ~116 kDa protein representing HIF-1 alpha after hypoxic induction in COS cells. Immunofluorescence staining of HIF-1 alpha in COS-7 cells with MA1-516 yields nuclear staining after exposing cells to 1% oxygen for 4 hours. In gel shift assays, MA1-516 has been successfully used only with mouse HIF-1 alpha.
Antibodies to this protein (and modification) were previously sold as part of a Thermo Scientific Cellomics High Content Screening Kit. This replacement antibody is now recommended for researchers who need an antibody for high content cell based assays. It has been thoroughly tested and validated for cellular immunofluorescence (IF) applications. Further optimization including the selection of the most appropriate fluorescent Dylight conjugated secondary antibody may have to be performed for your high content assay.
Oxygen availability plays a major role in the regulation of expression of many different genes including erythropoietin, nitric oxide synthase (NOS), heme oxygenase 1 (HO-1), glucose transporters and vascular growth factors necessary for the maintenance of homeostasis in hypoxic conditions. Hypoxia-inducible factor 1 alpha (HIF-1 alpha) has been identified as a bHLH-PAS family member which is instrumental in the oxygen-dependent regulation of these genes. HIF-1 alpha rapidly accumulates in the nucleus upon exposure to hypoxic conditions where it heterodimerizes with the aryl hydrocarbon nuclear receptor translocator, ARNT, also referred to as HIF-1 beta.
