  Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) - Anti-HIF-1 alpha antibody [EP1215Y] - BSA and Azide free (ab210073)

  Immunohistochemical analysis of Formalin-fixed paraffin-embedded human CRC tumour tissue using Anti-HIF-1 alpha antibody [EP1215Y] ab51608 for HIF-1 alpha staining. Endogenous peroxidase of sections was inhibited by 7.5% H₂O₂ at room temperature

  In central tumor areas of human CRCs β-catenin was typically localized at the cell membrane (A) whereas only a weak staining was observed for cytoplasmic GRP78 (B) and HIF-1 alpha staining was found to be negative (C). At the invasion front strong nuclear β-catenin was detectable indicating EMT (D, G). In corresponding regions strong cytoplasmic GRP78 expression was found (E, H). In some of the cases an intense nuclear HIF-1 alpha staining was observed (F, with hypoxia), but not in others (I, without hypoxia) (magnification 200×; scale bar: 100 µm).

  HIF-1 alpha Immunocytochemistry/ Immunofluorescence staining of HeLa cells using rabbit Anti-HIF-1 alpha antibody

  HeLa cells were untreated or treated with 1mM Deferoxamine (DFO) for 24h and fixed with paraformaldehyde for imaging by fluorescent microscopy. Cells were blocked and stained with 1X blocking buffer (10X Blocking Buffer ab126587). Unpurified Anti-HIF-1 alpha antibody [EP1215Y] ab51608 was used at 1:500. DAPI was used to label the nucleus. HIF1 alpha staining is absent in untreated cells and induced by DFO treatment. HIF1 alpha localizes to the nucleus.
