title: X-ray diffraction study of fast and slow mammalian skeletal muscle in the live relaxed state.
abstract: Experimental methods have been developed by which fast and slow muscles of the mouse can be maintained in good condition for the time needed to record detailed X-ray patterns. The results presented here show that thick filaments of both types of fibre show only minor differences from those of frog muscle. However, in slow muscle alone a remarkable transformation of this structure can occur.
