  • Function

    Component of the ubiquinol-cytochrome c reductase complex (complex III or cytochrome b-c1 complex), which is a respiratory chain that generates an electrochemical potential coupled to ATP synthesis.
  • Involvement in disease

    Defects in MT-CYB are a rare cause of mitochondrial dysfunction underlying different myopathies. They include mitochondrial encephalomyopathy, hypertrophic cardiomyopathy (HCM), and sporadic mitochondrial myopathy (MM). In mitochondrial myopathy, exercise intolerance is the predominant symptom. Additional features include lactic acidosis, muscle weakness and/or myoglobinuria. Defects in MTCYB are also found in cases of exercise intolerance accompanied by deafness, mental retardation, retinitis pigmentosa, cataract, growth retardation, epilepsy (multisystem disorder).
    Cardiomyopathy, infantile histiocytoid
    Leber hereditary optic neuropathy
  • Sequence similarities

    Belongs to the cytochrome b family.
  • Cellular localization

    Mitochondrion inner membrane.

Thank you forcontacting Abcam about ab81215, anti-MT-CYB antibody I am sorry to hear that you are experiencing problems with this antibody.  It is covered under our Abpromise, which guarantees that it will work on human tissue in western blot. I know that you have tried a few different variations but there I do have a few suggestions/questions: 1 - What type of tissue samples are you using? Do you use a positive control? 2 - It is recommenced to use this antibody at a concentration of 1ug/ml? Have you tried this concentration? 3 - What concentration of protein are you loading into your gel?  4 - Are you using detergent in your wash buffer? If so, is it Tween, Triton X-100? If you do use these detergents, lowering the concentration would help. I know that you have most probably tried variations of these suggestions but I would be grateful if you could let me know what you have tried, so that we can have it in our records. As I said previously, this antibody is covered under our Abpromise and so if we cannot resolve the issues with this particular vial, then I would be happy to send you a new vial from a different lot. I look forward to your reply.
