Table 1. Summary of protein concentrations for Laminin, α-dystroglycan and dystrophin in mouse skeletal muscle extracts (SKM) and rabbit crude surface membrane preparations (CSM).

	SKM	CSM
	Concentration (nmol/g SKM protein)	Concentration (nmol/g CSM protein)
Laminin	2.20 ± 0.22	N/A
α-Dystroglycan	89.72 ± 15.04	692.67 ± 57.39
Dystrophin	2.20 ± 0.07	16.11 ± 0.69
Ratio	Lam : αDG : Dys = 1 : 41 : 1	αDG : Dys = 43 : 1

The concentrations are shown as mean ± standard error with the unit of nmol per g of total mouse skeletal muscle protein (SKM) or rabbit crude surface membrane protein (CSM).
