The localisation of carletinin in the midbrains of 10 sexually mature chinchilla males was examined by carrying out the peroxidase-antiperoxidase immunocytochemical reaction using specific monoclonal antibody against calretinin. Intensive immunostaining for the protein was observed in the majority of fusiform, pyramidal, and stellate neurons of dorsal raphe nucleus. A similar calretinin distribution in neurons of this region to those observed in primates and rodents was demonstrated.
