Transcriptional profiling from adult Scyliorhinus retifer from electrosensory cells of the ampullae of Lorenzini, forebrain, skin, and skeletal muscle shows differential gene expression of voltage-activated ion channels related to sensory transduction. Overall design: Examination of gene expression in ampullary cells, brain, non-electroreceptive skin, and muscle in one adult Scyliorhinus retifer chain catshark prepared from poly A+ RNA using Illumina TruSeq Stranded mRNA Library Prep Kit
