Identification and distribution of nitric oxide synthase in the brain of adult Antarctic Teleosts
We investigated the presence of nitric oxide synthase (NOS) in brain of adult Antarctic teleosts by indirect immunofluorescence technique using a synthetic rat neuronal NOS (nNOS) antibody. The following species were examined: Trematomus bernacchii, Gymno- draco acuticeps, Histiodraco velifer, Cygno...
