Expression of β-gal protein in mice that received DNA immunization. BALB/c mice were injected with or without cardiotoxin at thigh muscles and then with pcDNA3/β-gal (10 or 50 μg) at the same muscles 5 days later. The thigh muscles were stained with the X-gal staining 5 days after DNA immunization.
