  Simple Western: HIF-1 alpha Antibody - BSA Free TA336260 - Image shows a specific band for HIF-1 alpha in 0.2 mg/mL of Hypoxic HeLa lysate. This experiment was performed under reducing conditions using the 12-230 kDa separation system.

  P53 was increased response to IR in the fetal brain.Even though no significant change in protein level, total p53 and phosphorylation of P53 at ser15 were increased compared with HIF-1α in fetal brains response to IR. Numbers in the pictures show the average of three independent experiments (n = 3 from 3 individual pregnant mice).

  Immunohistochemistry-Paraffin: HIF-1 alpha Antibody - BSA Free TA336260 - Analysis of FFPE tissue section of human endometrium carcinoma AN3CA cell line based xenograft using rabbit polyclonal HIF-1 alpha antibody TA336260 at 1:300 dilution. The signal was developed using HRP-labelled secondary antibody and DAB reagent, and the section was further counterstained using hematoxylin. The tested section depicted mainly a diffused cytoplasmic staining but there were some cells which showed nuclear signal also (representing hypoxic cells).

  Simple Western: HIF-1 alpha Antibody - BSA Free TA336260 - Simple Western lane view shows lysates of MCF +/- DMOG, BioSpherix MSCs in hypoxic conditions, and BioSpherix MSCs in normoxic conditions loaded at 0.5 mg/ml. A band was detected for HIF-1 alpha at approximately 116 kDa (as indicated) using TA336260 (1:100 dilution) followed by Anti-Rabbit Secondary Antibody (042-206, ProteinSimple). This experiment was conducted under standard assay conditions, and using the 12-230 kDa separation module (SW-W004). Non-specific interaction with the 230 kDa Simple Western standard may be seen with this antibody. Image from an internal validation.

  Dual RNAscope ISH-IHC: HIF-1 alpha Antibody - BSA Free TA336260 - Formalin-fixed paraffin-embedded tissue sections of human kidney were probed for HIF-1 alpha mRNA (ACD RNAScope Probe, catalog #605228; Fast Red chromogen, ACD catalog # 322750). Adjacent tissue section was processed for immunohistochemistry using Rabbit Polyclonal (Novus Biologicals catalog # TA336260) at 1:500 dilution with one-hour incubation at room temperature followed by incubation with anti-rabbit IgG VisUCyte HRP Polymer Antibody (Catalog # VC003) and DAB chromogen (yellow-brown). Tissue was counterstained with hematoxylin (blue). Specific staining was localized to cytoplasm of tubules.

• Background: HIF-1 alpha (HIF1A) is a nuclear protein involved in mammalian oxygen homeostasis. This occurs as a posttranslational modification by prolyl hydroxylation. HIF-1 is a heterodimer composed of HIF-1 alpha and HIF-1 beta subunits. Both subunits are constantly translated. However, under normoxic conditions, human HIF-1 alpha is hydroxylated at Pro402 or Pro564 by a set of HIF prolyl hydroxylases, is polyubiquinated, and eventually degraded in proteosomes. Under hypoxic conditions, the lack of hydroxylation prevents HIF degradation and increases transcriptional activity. Therefore, the concentration of HIF-1 alpha increases in the cell.
• Synonyms: bHLHe78; HIF-1-alpha; HIF-1A; HIF-1alpha; HIF1; HIF1-ALPHA; MOP1; PASD8
• Note: This HIF-1 alpha antibody is useful for Chromatin Immunoprecipitation (PMID 22891341), Immunohistochemistry, Western Blot, Gel Shift Assays, Immunocytochemistry/Immunfluorescence (PMID: 21270095; 21270095), and Immunoprecipitation. In Western blot a band is observed ~120 kDa. IHC applications have been mixed on mouse. For ChIP, nuclear extracts are recommended. Prior to immunostaining paraffin tissues, antigen retrieval with sodium citrate buffer (pH 6.0) is recommended.
