Figure 3.
RT–PCR analysis of predicted cassette exons shows brain- and/or heart/muscle-specific splicing. Exon inclusion level was measured in six human tissues by radioactive RT–PCR. In each panel, the quantified exon inclusion level and the number of conserved UIF, exonic, and DIF UGCAUG elements are indicated above and below the gene symbol, respectively. The size of each PCR product is also indicated.
