IHC-P Use at an assay dependent concentration.


  • FunctionCoup (chicken ovalbumin upstream promoter) transcription factor binds to the ovalbumin promoter and, in conjunction with another protein (S300-II) stimulates initiation of transcription. Binds to both direct repeats and palindromes of the 5'-AGGTCA-3' motif. Represses transcriptional activity of LHCG.
  • Sequence similaritiesBelongs to the nuclear hormone receptor family. NR2 subfamily.
    Contains 1 nuclear receptor DNA-binding domain.
  • Cellular localizationNucleus.

    Developed using the ECL technique

    Performed under reducing conditions.

    Predicted band size : 46 kDa
    Observed band size : 48 kDa (why is the actual band size different from the predicted?)

    Exposure time : 150 seconds
  • Overlay histogram showing SH-SY5Y cells stained with ab41858 (red line). The cells were fixed with 80% methanol (5 min) and then permeabilized with 0.1% PBS-Tween for 20 min. The cells were then incubated in 1x PBS / 10% normal goat serum / 0.3M glycine to block non-specific protein-protein interactions followed by the antibody (ab41858, 1µg/1x106 cells) for 30 min at 22ºC. The secondary antibody used was DyLight® 488 goat anti-mouse IgG (H+L) (ab96879) at 1/500 dilution for 30 min at 22ºC. Isotype control antibody (black line) was mouse IgG2a [ICIGG2A] (ab91361, 1µg/1x106 cells) used under the same conditions. Acquisition of >5,000 events was performed.
