Expression of ChAT mRNA in the striatum and retina revealed by RT-PCR. A, Schematic drawing showing the exon organizations of cChAT and pChAT, as well as the positions of primers used. B, A 3% agarose gel showing the result of the first RT-PCR and the nested PCR for ChAT. Lane 1, Striatum (First PCR); lane 2, retina (First PCR); lane 3, striatum (Nest PCR); lane 4, retina (Nest PCR). The positions of DNA size markers (1 kb DNA ladder; Invitrogen) and those of positive bands are indicated to the left and right of the gel, respectively.
