The Oxygen Receptor of the Teleost Gill?
Abstract The gills of the Atlantic cod, Gadus morhua , were studied using immunohistochemical techniques. Primary antibodies directed against serotonin (5‐hydroxytryptamine, 5‐HT) and acetylated α‐tubulin were used to visualise cells containing serotonin and nerve fibres, respectively. Three morphol...
