By means of molecular biology techniques the structures of rat and bovine galanin have also been deduced [4,5].The three animal forms are identical with respect to the first IS residues but differ at several positions in the C-terminal part.. The sequence of human galanin is not known, but the molecule does not react with antisera against the C-terminal region of porcine galanin, GAL-LI, galanin-like immunoreactivity; HPLC, high performance liquid chromatography; ACN, acetonitrile; TFA, trifluoroacetic acid; HFBA, heptafluorobutyric acid; PTH, phenylthiohydantoin; PDMS, plasma desorption mass spectrometryPublished by Elsevier Science Publishers B.
