  • Function
    Desmin are class-III intermediate filaments found in muscle cells. In adult striated muscle they form a fibrous network connecting myofibrils to each other and to the plasma membrane from the periphery of the Z-line structures.
  • Involvement in disease
    Defects in DES are the cause of myopathy myofibrillar desmin-related (MFM-DES) [MIM:601419]; also known as desmin-related myopathy (DRM). A neuromuscular disorder characterized by skeletal muscle weakness associated with cardiac conduction blocks, arrhythmias, restrictive heart failure, and by myofibrillar destruction with intracytoplasmic accumulation of desmin-reactive deposits in cardiac and skeletal muscle cells.
    Defects in DES are the cause of cardiomyopathy dilated type 1I (CMD1I) [MIM:604765]. Dilated cardiomyopathy is a disorder characterized by ventricular dilation and impaired systolic function, resulting in congestive heart failure and arrhythmia. Patients are at risk of premature death.
    Defects in DES are the cause of neurogenic scapuloperoneal syndrome Kaeser type (Kaeser syndrome) [MIM:181400]. Kaeser syndrome is an autosomal dominant disorder with a peculiar scapuloperoneal distribution of weakness and atrophy. A large clinical variability is observed ranging from scapuloperoneal, limb grindle and distal phenotypes with variable cardiac or respiratory involvement. Facial weakness, dysphagia and gynaecomastia are frequent additional symptoms. Affected men seemingly bear a higher risk of sudden, cardiac death as compared to affected women. Histological and immunohistochemical examination of muscle biopsy specimens reveal a wide spectrum of findings ranging from near normal or unspecific pathology to typical, myofibrillar changes with accumulation of desmin.

Thank you for clarifying this information. As you have had good results with the other lot I believe the problems is with the vial you received and I would be happy to offer you a replacement vial if the antibody was purchased in the last 120 days. If you could please provide your order details I can arrange a free order for you, I look forward to hearing from you,

Thank you for contacting us for technical support regarding your recent problem with a vial of ab8976. I'm sorry to hear you are experiencing problems with this vial and I would appreciate if you could please clarify which vial is not working for you. According to your orders you have received two tubes: lot 256477 is the most recent one (the one you said worked well) was ordered a month ago lot 225987 was ordered in December 2006 (the one you said did not work). Is this correct or is it the opposite happening i.e. the new vial is not working? Thank you very much for clarifying, I look forward to hearing from you to resolve this matter,

Thank you for your email. I would expect for you to detect desmin in your samples, smooth muscle cells, and you certainly have tried high enough concentrations of ab8976. How long did you incubate with the primary? I would suggest incubating overnight at 4C. Other than that, your protocol looks fine to me. We have not had any other complaints regarding this product, and there is a possibilty that the vial you received had gone off during the shipping process. I can offer to send you a free of charge replacement vial of ab8976 or can offer you a credit note or refund. Please let me know which you would prefer.
