Our Abpromise guarantee covers the use of ab100956 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 µg/ml. Detects a band of approximately 35 kDa (predicted molecular weight: 31 kDa).


  • Function
    Forms a channel through the mitochondrial outer membrane that allows diffusion of small hydrophilic molecules. The channel 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.
  • Tissue specificity
    Expressed in all tissues examined.
  • Sequence similarities
    Belongs to the eukaryotic mitochondrial porin family.
  • Domain
    Consists mainly of a membrane-spanning beta-barrel formed by 19 beta-strands.
  • Cellular localization
    Mitochondrion outer membrane.

  • All lanes : Anti-VDAC2 antibody (ab100956) at 1 µg/ml (Milk Blocked - 3%)

    Lane 1 : Human brain tissue lysate - total protein (ab29466)
    Lane 2 : HeLa (Human epithelial carcinoma cell line) Whole Cell Lysate
    Lane 3 : HepG2 (Human hepatocellular liver carcinoma cell line) Whole Cell Lysate

    Lysates/proteins at 25 µg per lane.

    All lanes : Goat Anti-Rabbit IgG H&L (HRP) preadsorbed (ab97080) at 1/5000 dilution

    Developed using the ECL technique.

    Performed under reducing conditions.

    Predicted band size: 31 kDa
    Observed band size: 35 kDa (why is the actual band size different from the predicted?)
    Additional bands at: 16 kDa, 58 kDa. We are unsure as to the identity of these extra bands.

    Exposure time: 20 minutes

    The predicted molecular weight of VDAC2 is 31 kDa (SwissProt), however we expect to observe a banding pattern around 35 kDa. Abcam welcomes customer feedback and would appreciate any comments regarding this product and the data presented above.
