Immunochemical comparison of myosin light chains from chicken fast white, slow red, and cardiac muscle.
Antibodies were formed against the myosin light chains isolated from chicken fast skeletal, slow skeletal, and cardiac muscle and the antigenicities of the light chains were compared by double immunodiffusion and immunoelectrophoresis. It was shown that fast light chains are immunologically different from light chains of slow and cardiac myosin, while the slow and cardiac muscle light chains have similar immunological characteristics; that is, the light chains of apparent molecular weight about 27,000 daltons in SDS-acrylamide gel electrophoresis of slow and cardiac muscle are immunologically indistinguishable, and the other light chains of apparent molecular weight about 19,000 daltons of both muscles include a common antigenic site.
