in order to set up specific radioimmunoassays for the two n- and c-terminal tetradecapeptides of somatostatin-28 the peptides somatostatin ss14 and ss28 and the somatostatin by-products 1-tyr-ss14 , 11-tyr-14 and desaminotyrosyl-beta-alanine fragment ( 1 -- -- 14 ) of ss28 were radioiodinated by the chloramine-t or bolton-hunter techniques .
