Our Abpromise guarantee covers the use of ab97931 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
IHC-P Use a concentration of 5 µg/ml. Perform heat mediated antigen retrieval before commencing with IHC staining protocol.
WB Use at an assay dependent concentration. Detects a band of approximately 30 kDa (predicted molecular weight: 33 kDa).


  • Function
    UCP are mitochondrial transporter proteins that create proton leaks across the inner mitochondrial membrane, thus uncoupling oxidative phosphorylation from ATP synthesis. As a result, energy is dissipated in the form of heat.
  • Tissue specificity
    Widely expressed in adult human tissues, including tissues rich in macrophages. Most expressed in white adipose tissue and skeletal muscle.
  • Sequence similarities
    Belongs to the mitochondrial carrier family.
    Contains 3 Solcar repeats.
  • Cellular localization
    Mitochondrion inner membrane.

    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 : 33 kDa
    Observed band size : 30 kDa (why is the actual band size different from the predicted?)
    Additional bands at : 100 kDa. We are unsure as to the identity of these extra bands.

    Exposure time : 3 minutes
  • IHC image of ab97931 staining in human lymph node formalin fixed paraffin embedded tissue section, performed on a Leica BondTM system using the standard protocol F. The section was pre-treated using heat mediated antigen retrieval with sodium citrate buffer (pH6, epitope retrieval solution 1) for 20 mins. The section was then incubated with ab97931, 5µg/ml, for 15 mins at room temperature and detected using an HRP conjugated compact polymer system. DAB was used as the chromogen. The section was then counterstained with haematoxylin and mounted with DPX.

    For other IHC staining systems (automated and non-automated) customers should optimize variable parameters such as antigen retrieval conditions, primary antibody concentration and antibody incubation times.
