we studied the molecular forms of somatostatin-like immunoreactivity ( sli ) , newly released from isolated perfused preparations of the porcine antrum , stomach , pancreas and upper small intestine : perfusion effluents were concentrated by sep-pak c-18 adsorption , eluted with ethanol , dessicated , and subjected to gel filtration with subsequent radioimmunoassays for somatostatin-14 and n-terminal somatostatin-28 immunoreactivity .
