Distribution of freeze-fracture particle sizes in Duchenne muscle plasma membrane.
We studied the distribution of freeze-fracture intramembranous particle (IMP) sizes in Duchenne muscle biopsies and controls. We found that the previously reported decrease in muscle plasma membrane particle density in Duchenne includes a variety of different IMPs, but does not preferentially involve IMPs of any one size.
