• Product name
  • Description
    Rabbit polyclonal to HIF1AN
  • Host species
  • Specificity
    The expected molecular weight of FIH is 40 kDa. A band corresponding to this size is seen on the western blot analysis, and is competed away by the addition of FIH blocking peptide. A smaller band is seen, which is also competed away by the blocking peptide. In the A431 extract a nonspecific band of approximately 50 kDa is seen, which is not diminished by the addition of blocking peptide.
  • Tested applications
    Suitable for: IHC-FoFr, ICC/IF, WBmore details
  • Species reactivity
    Reacts with: Chicken, Human
  • Immunogen

    Synthetic peptide derived from within residues 250 to the C-terminus of Human FIH/asparagine hydroxylase.


  • Positive control
    • This antibody gave a positive signal in the following whole cell lysates: HeLa; Jurkat; A431; Hek293 and Hela Nuclear lysate.



Our Abpromise guarantee covers the use of ab12289 in the following tested applications.

The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.

Application Abreviews Notes
  • Application notes
    ICC/IF: Use at a concentration of 5 µg/ml.
    WB: 1/500. Detects a band of approximately 40 kDa (predicted molecular weight: 40 kDa). Can be blocked with FIH peptide (ab12306).

    Not yet tested in other applications.
    Optimal dilutions/concentrations should be determined by the end user.
  • Target

    • Function
      Hydroxylates HIF-1 alpha at 'Asp-803' in the C-terminal transactivation domain (CAD). Functions as an oxygen sensor and, under normoxic conditions, the hydroxylation prevents interaction of HIF-1 with transcriptional coactivators including Cbp/p300-interacting transactivator. Involved in transcriptional repression through interaction with HIF1A, VHL and histone deacetylases.

    • ICC/IF image of ab12289 stained human Hek293 cells. The cells were 4% PFA fixed (10 min), permabilised in TBS-T (20 min) and incubated with the antibody (ab12289, 5µg/ml) for 1h at room temperature. 1%BSA / 10% normal goat serum / 0.3M glycine was used to quench autofluorescence and block non-specific protein-protein interactions. The secondary antibody (green) was Alexa Fluor® 488 goat anti-rabbit IgG (H+L) used at a 1/1000 dilution for 1h. Alexa Fluor® 594 WGA was used to label plasma membranes (red). DAPI was used to stain the cell nuclei (blue).
