Fig. 7. Isolation of the dystrophin-dystroglycan complex of the K19–/– mouse. The dystrophin-dystroglycan complex was partially purified on a wheat germ lectin affinity column, eluted, and analyzed by SDS-PAGE and immunoblotting, as described in Materials and Methods. K19, K8 and
-actin eluted with dystrophin (Dys) and β-dystroglycan (Bdg) from control tissue, but only
-actin eluted with these proteins from K19–/– tissue.
