Figure 1From: Characterizing exons 11 and 1 promoters of the mu opioid receptor (Oprm) gene in transgenic miceSchematic of the transgenic construct. Exons and introns are shown by black boxes and horizontal lines, respectively. The reporter cassettes are indicated by white boxes. The E11 and E1 promoters are shown by arrows. LoxP sites are shown by triangles. The fragments generated by the RT-PCR are indicated by double-head arrows labeled with the predicted sizes. i: IRES.Back to article page
