Evidence for the presence of ASIC-encoding mRNA in the rat retina. Whole retinal RNA was subject to RT-PCR using primers designed to detect the first six ASIC subunits cloned to date. Positive controls were performed using rat brain or DRG cDNA as appropriate. All RT-PCR experiments were repeated with the omission of reverse transcriptase to provide negative controls containing only genomic DNA rather than cDNA. Arrows indicate size of bands expected in RT+ samples.
