RT-PCR of components of the nnCS in mouse tracheal epithelial cells. (A) RT-PCR of ChAT in mouse tracheal epithelial cells. RT-PCR experiments showed a prominent ChAT band at about 200 bp with two different primers (ChAT₁, ChAT₂). H₂O control is without template (M: size marker). (B) RT-PCR of OCT in mouse tracheal epithelium. Depicted are RT-PCR results of OCT1-3 from two of three mice. A RT-PCR product for OCT1 and OCT3 was visible at a size of about 200 bp in all tissue samples. For OCT2 the band at 200 bp only occurred in two out of three tissue samples. GAPDH and H₂O denote the controls (M: size marker).
