Our Abpromise guarantee covers the use of ab36833 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
WB Use a concentration of 0.5 - 1 µg/ml. Predicted molecular weight: 11.6 (mouse), 6 (human) kDa.Can be blocked with Human Noxa peptide (ab39823).
IHC-P Use a concentration of 1 µg/ml.
ICC/IF Use a concentration of 1 - 5 µg/ml.


  • Function
    Promotes activation of caspases and apoptosis. Promotes mitochondrial membrane changes and efflux of apoptogenic proteins from the mitochondria. Contributes to p53/TP53-dependent apoptosis after radiation exposure. Promotes proteasomal degradation of MCL1. Competes with BAK1 for binding to MCL1 and can displace BAK1 from its binding site on MCL1 (By similarity). Competes with BIM/BCL2L11 for binding to MCL1 and can displace BIM/BCL2L11 from its binding site on MCL1.
  • Tissue specificity
    Highly expressed in adult T-cell leukemia cell line.
  • Sequence similarities
    Belongs to the PMAIP1 family.
  • Domain
    The BH3 motif is essential for pro-apoptotic activity.

  • Anti-Noxa antibody (ab36833) at 0.5 µg/ml + Human stomach cell lysate

    Predicted band size: 11.6 (mouse), 6 (human) kDa
    Observed band size: 15 kDa (why is the actual band size different from the predicted?)

  • ab36833 at 1µg/ml staining Noxa in human stomach tissue by IHC

  • ICC/IF image of ab36833 stained HeLa cells. The cells were 100% methanol fixed (5 min) and then incubated in 1%BSA / 10% normal goat serum / 0.3M glycine in 0.1% PBS-Tween for 1h to permeabilise the cells and block non-specific protein-protein interactions. The cells were then incubated with the antibody (ab36833, 1µg/ml) overnight at +4°C. 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) at a 1/200 dilution for 1h. DAPI was used to stain the cell nuclei (blue) at a concentration of 1.43µM.
