Fig. 7. MHC and MLC isoform composition varied substantially along the length of single fibres. MHC isoform content and MLC3/MLC1 ratio were determined in 1 mm segments along the full length of single fibres (N=10) by quantitative densitometry of gels after SDS-PAGE. All fibres were obtained from the anterior tibialis muscle. Each letter (AJ) represents a different fibre.
