The present studies were undertaken to confirm reports of high concentrations of the C-terminal tetrapeptide of gastrin in hog antral mucosa. A method was developed whereby synthetic tetrapeptide added to boiling water extracts of hog antral mucosa could be purified to homogeneity by adsorption to Amberlite XAD2 resin, ion exchange chromatography on DEAE cellulose, and reverse phase HPLC. The product had the amino acid composition of gastrin tetrapeptide. When the same method was used on antral mucosa without prior addition of synthetic G4, several small peaks of material with C-terminal immunoreactivity could be found in DEAE column eluates but none could be unequivocally identified as the tetrapeptide. In the same column runs there was a relatively large peak of immunoreactivity eluting later than the tetrapeptide. This material was purified to homogeneity by HPLC and on the basis of its amino acid composition and sequence was identified as the C-terminal hexapeptide of gastrin.
