  • General notes
    Mitochondrial membrane proteins have been shown to be involved in several cellular processes such as the regulation of apoptosis and the energy metabolism. Cardiotin antibodies, which are reactive with mitochondrial proteins, have proven to be early indicators of ischemia induced changes in the myocardium.



Our Abpromise guarantee covers the use of ab8962 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 at an assay dependent dilution.
IHC-Fr Use at an assay dependent dilution.
WB 1/25 - 1/500.


  • Relevance
    Cardiotin is a high molecular weight protein complex (300 kDa) located in the mitochondrial membrane. The cardiotin structure exists as subunits of 60 kDa and 100 kDa. Both subunits contain the same amino-terminal 14 amino-acid sequence, showing high homology to human skeletal muscle a-actinin, suggesting that the tetrameric configuration of the cardiotin protein structure is a transmembrane complex with the N-terminus at the cytoplasmic side of the membrane, able to interact with actin. During cardiac contractile dysfunction, the cardiotin distribution is affected in pathlogical cardiomyocytes i.e. chronic ischemic myocardium. This monoclonal antibody can be used in immunohistochemistry for the detection of a disturbed mitochondrial activity in cardiomyocytes i.e. during chronic ischemia or chronic atrial fibrillation.
