Our Abpromise guarantee covers the use of ab61273 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 1 - 5 µg/ml. Predicted molecular weight: 31 kDa. This antibody has only been tested in WB against the recombinant fragment used as immunogen. We have no data on the detection of endogenous protein.
Flow Cyt Use 0.5µg for 106 cells. ab170191-Mouse monoclonal IgG2a, is suitable for use as an isotype control with this antibody.
ELISA Use at an assay dependent concentration.


  • FunctionForms a channel through the mitochondrial outer membrane and also the plasma membrane. The channel at the outer mitochondrial membrane allows diffusion of small hydrophilic molecules; in the plasma membrane it is involved in cell volume regulation and apoptosis. It adopts an open conformation at low or zero membrane potential and a closed conformation at potentials above 30-40 mV. The open state has a weak anion selectivity whereas the closed state is cation-selective. May participate in the formation of the permeability transition pore complex (PTPC) responsible for the release of mitochondrial products that triggers apoptosis.
  • Tissue specificityHeart, liver and skeletal muscle.
  • Sequence similaritiesBelongs to the eukaryotic mitochondrial porin family.
  • DomainConsists mainly of a membrane-spanning beta-barrel formed by 19 beta-strands. The helical N-terminus folds back into the pore opening and plays a role in voltage-gated channel activity.
  • Cellular localizationMitochondrion outer membrane. Cell membrane.

  • Predicted band size : 31 kDa
    Western blot against tagged recombinant protein immunogen using ab61273 VDAC / Porin antibody at 1ug/ml. Predicted band size of immunogen is 37 kDa.
  • Overlay histogram showing HepG2 cells stained with ab61273 (red line). The cells were fixed with 4% paraformaldehyde (10 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 (ab61273, 0.5µg/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. This antibody gave a positive signal in HepG2 cells fixed with 80% methanol (5 min)/permeabilized with 0.1% PBS-Tween for 20 min used under the same conditions.
