Analysis of skeletal and cardiac muscle from desmin knock-out and normal mice by high resolution separation of myosin heavy-chain isoforms.

In this study, using a modified electrophoretic technique, we have defined in the mouse the myosin heavy-chain composition of both newborn and adult skeletal and cardiac muscles. Using this high resolution technique it was possible to detect modifications in the myosin heavy-chain expression in both cardiac and skeletal muscles of desmin knock-out mice.
