Immunoreactivity of skate electrocytes towards monoclonal antibodies against human dystrophin and dystrophin-related (DMDL) protein

Monoclonal antibodies against human dystrophin have been used to demonstrate the existence of a dystrophin-like protein in the electrocytes of skate electric organ. This protein is also present in skate muscle and resembles that found in Torpedo electric organ. Monoclonal antibodies against a human autosomal homologue of dystrophin (DMDL protein) did not detect a similar protein in skate or Torpedo. Immumocytochemical staining of the innervated and non-innervated faces of the electrocyte membrane was obtained using the anti-dystrophin antibodies only.
