Immunohistochemical localisation of FMRF-amide-like peptide in the brain of icefish and red blooded Antarctic Teleosts
The distribution of Phe-Met-Arg-Phe-NH2 (FMRF-amide) -like immunoreactivity was investigated by indirect immunofluorescence technique using the molluscan FMRF-amide antibody in the brain of icefish (Pagetopsis macropterus and Chionodraco hamatus used as positive control) and red blooded (Trematomus...
