Figure 5. Voltage-gated α subunit mRNA expression in guinea pig tissues.

Quantitative real-time RT-PCR was used to determine expression of 9 sodium channel α subunits in a variety of guinea pig tissues. Tissues studied were nodose ganglia (n = 3), jugular ganglia (n = 3), dorsal root ganglia (n = 3), brain tissue (n = 2), heart (n = 3), and skeletal muscle (n = 2). Note that relative amounts of mRNA within a given tissue type are approximate as the relative efficiencies of the RT step for each of the 9 Na_Vs is unknown. Data are means ±s.e.m.
