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. Detects a band of approximately 26 kDa (predicted molecular weight: 30 kDa).
Flow Cyt Use 1µg for 106 cells.

ab170191 - Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.


  • Function
    Core subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) that is believed to belong to the minimal assembly required for catalysis. Complex I functions in the transfer of electrons from NADH to the respiratory chain. The immediate electron acceptor for the enzyme is believed to be ubiquinone.
  • Sequence similarities
    Belongs to the complex I 30 kDa subunit family.
  • Cellular localization
    Mitochondrion inner membrane.

    why is the actual band size different from the predicted?
    Additional bands at: 57 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 1 minute

    The band observed at 26 kDa could potentially be a cleaved form of NDUFS3 due to the presence of a 36 amino acid transit peptide.

  • Overlay histogram showing HepG2 cells stained with ab14711 (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 (ab14711, 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.

    Lane 1 : Isolated mitochondria from Human heart at 5 µg
    Lane 2 : Isolated mitochondria from Bovine heart at 4 µg
    Lane 3 : Isolated mitochondria from Rat heart at 10 µg
    Lane 4 : Isolated mitochondria from Mouse heart at 10 µg

    All lanes : Goat anti-Mouse IgG

    Predicted band size: 30 kDa
    Observed band size: 26 kDa why is the actual band size different from the predicted?

    Extra bands in the mouse sample (lane 4) are due to the reaction of the IgG-specific goat anti-mouse secondary antibody with residual mouse blood in the heart tissue, as it is very difficult to entirely remove the blood from these small organs.
