Panel A: Demonstration of PDE-5 mRNA in chorionic plate arterial rings. cDNA was prepared from RNA extracted from chorionic plate arterial rings, and amplified using specific primers for 400 bp regions of the indicated genes. PCR products were electrophoresed on 1% agarose. Panel B: Demonstration of PDE-5 protein in chorionic plate arterial rings. Human chorionic plate arterial rings homogenates, representing various amounts of protein, were examined by SDS-PAGE Western blot for the presence of PDE-5.
