Our Abpromise guarantee covers the use of ab3477 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
Flow Cyt 1/400.
WB Use a concentration of 1 µg/ml. Predicted molecular weight: 34 kDa.Can be blocked with UCP3 peptide (ab4994). By Western blot, this antibody detects an ~30 kDa protein representing UCP 3 from rat heart homogenate.


  • FunctionUCP are mitochondrial transporter proteins that create proton leaks across the inner mitochondrial membrane, thus uncoupling oxidative phosphorylation. As a result, energy is dissipated in the form of heat. May play a role in the modulation of tissue respiratory control. Participates in thermogenesis and energy balance.
  • Tissue specificityOnly in skeletal muscle and heart. Is more expressed in glycolytic than in oxidative skeletal muscles.
  • Involvement in diseaseDefects in UCP3 may be involved in obesity (OBESITY) [MIM:601665]. It is a condition characterized by an increase of body weight beyond the limitation of skeletal and physical requirements, as the result of excessive accumulation of body fat.
  • Sequence similaritiesBelongs to the mitochondrial carrier family.
    Contains 3 Solcar repeats.
  • Cellular localizationMitochondrion inner membrane.

Anti-UCP3 antibody images

  • ab3477 staining UCP3 in differentiated cardiac ventricular cells by Flow Cytometry. Cells were fixed with paraformaldehyde and permeabilized with permeabilization buffer. The sample was incubated with the primary antibody (1/400) for 12 hours at 4°C. An Allophycocyanin-conjugated goat polyclonal anti-rabbit IgG (1/1000) was used as the secondary antibody.
    Gating Strategy: Isotype negative control (white).

    ab3477 at a 1/1000 dilution in Western blot. The left hand lane shows the blot of a lysate from muscle mitochondria from a UCP3 knockout mouse, the middle lane shows the same preparation from a wild type mouse, whilst the right hand lane shows a lysate prepared from a wild type rat. An HRP conjugated donkey anti-rabbit antibody was used as the secondary.

Thank you for your reply.

Regarding the UCP3 results, I agree that the lower band would be the UCP# signal but I am not sure what the higher molecular weight band could be. It may just be non-specific binding of the antibody, or it may be pos...

Thank you for your call today and for letting us know about the trouble with ab3477. I am hopeful that the background bands will be reduced by loading less protein, further diluting the antibody, and switching to a BSA block. However, if the high backg...

Thank you for contacting Abcam. I have talked to the lab about ab3477 and they have informed me that it is not uncommon for UCP3 antibodies to detect several isoforms of UCP3 in mouse tissue; isoforms 1 & 3 are routinely detected by the antibody. It ma...
