Abstract
An overall procedure for the determination of myoglobin in muscle biopsy specimens by a radioimmunoassay is described. The coefficient of variation in routine analysis averaged 18%. The mean myoglobin content in leg skeletal muscle of 13 females and 18 males was 4.7mg/g wet weight. There were no sex differences but the levels for elderly subjects (56—80 years) were slightly higher than those observed in younger persons (19—39 years).
