Figure 2

Northern blot analysis of Fluc RNA. Phosphorimage of northern blot of RNA recovered from DNA transfection of the dicistronic constructs containing L1 (A) or TrkB (B) sequences as indicated. Blots were hybridized to Fluc. The positions of size standards run in the adjacent lane are indicated. Full-length dicistronic transcripts are indicated by the arrows; the truncated TrkB Fluc transcript from the cryptic promoter is indicated by the open arrowhead. The coding sequence for Fluc is 1656 nt.
