(A) Agarose gel electrophoresis of RT-PCR products for BK channel subunits in the CB, the SCG, and the carotid artery (Artery). Multiplex PCR was performed for β-actin, BKα, BKβ2, and BKβ4. (B) Semi-quantitative analysis of gene expression for BK subunits was shown. The density of the each band was measured and normalized relative to the expression of β-actin in the same sample. Note that no strain differences were observed in the SCG (n = 5) and the artery (n = 4).
