title: Coexistence of cardiac-type and fast skeletal-type myosin light chains in embryonic chicken cardiac muscle.
abstract: Myosin from embryonic chicken ventricle contained a light chain component which comigrated with fast skeletal myosin light chain 1 (Lf1) on two dimensional electrophoresis in addition to cardiac type light chains (Lc1 and Lc2). Immunoblot analysis showed that this minor light chain band reacted with anti-Lf1 antibody. Antigens binding with anti-Lc1 and anti-Lf1 antibodies were located on myofibrils in embryonic cardiac muscle cells in vivo and in vitro. From these observations, we conclude that a small amount of Lf1 exists in embryonic chicken cardiac muscle.
