comparisons with glicentin 1-61 , produced by controlled , stepwise , consecutive digestion of purified natural glicentin with carboxypeptidases ( carboxypeptidase a followed by carboxypeptidase b , and again by carboxypeptidase a and b ) , gel filtration , ion exchange chromatography , reverse phase hplc and radioimmunoassays for the glucagon sequences 6-15 and 19-29 and for the glicentin sequence 12-30 all indicate that glicentin 1-61 constitutes approximately 57 % of the large mr glucagon-related peptides found in uraemia in pigs .
