ANXA7 junction probe intensities for all possible pairwise combinations of exons hybridized with (a) smooth muscle and (b) skeletal muscle samples. Probes are 40 nucleotides, centrally positioned, and the hybridization used 35% formamide. Intensities have been normalized by the corresponding 'edge probe' intensities (see text) and the maximum in each plot is scaled to one. The 5' exon of each pair is numbered on the vertical axis, and the 3' exon on the horizontal axis.
