Amplification of dystrophin exons 13–50, RNA extracted from treated and untreated mdx muscle. Primer set 4 inner (Table 1) was used for nested PCR amplification. The identity of the alternatively spliced products is shown with the reading frame indicated. Lanes 3, 4, 7 and 9 correspond to the samples used in Figure 5a lanes 2–5.
