Schematic representation of the Gtx-luciferase
reporter plasmids. The Gtx sequences are indicated as a open bar, the
luciferase sequences as a shaded bar, the poly(A) signal as a hatched
bar, the simian virus 40 promoter as a solid arrow, the simian virus 40
enhancer as a solid bar, and the T7 promoter as a shaded arrow. The Gtx
mRNA sequence at nucleotides 129–177 is written below the schematic.
Below this sequence are indicated the modifications present in the
other constructs. A vertical line indicates nucleotides identical to
those in Gtx-w, and a dash indicates a deleted
nucleotide.
