SOD1^G93A mutant protein is expressed in transplanted muscles.

Western blots showing reactivity of antibodies against mouse SOD1 protein (αM-SOD1) and against human SOD1 protein (αH-SOD1) which is used to label the human mutant SOD1 protein. Lanes are as follows: 1. B6.SOD1 transgenic MG muscle; 2. Wild-type MG muscle; 3. MG muscle from B6.SOD1 transgenic transplanted 2 months earlier into a wild-type animal; 4. Control muscles were obtained from the ipsilateral limb (soleus).
