Melanopsin in Lower Vertebrates: The Race Is On to Show that It Is Really There
The retina of the Antarctic teleost Trematomus bernacchii was examined immunocytochemically, using antisera against bovine rhodopsin (1:1,000) and visinin (1:250). There were no surprises with regard to rhodopsin, but positive visinin reactions occurred not only in the cones (visinin has a broad ran...
