A High Pressure Liquid Chromatography-Radioimmunoassay Method for Measurement of Cholecystokinin-8 and Cholecystokinin-33/39 in Plasma

摘要

A new high pressure liquid chromatography-radioimmunoassay method is described for the measurement of cholecystokinin-8 (CCK-8) and CCK-33/39 in plasma. The plasma levels of CCK-8-sulfate, CCK-8-desulfate, and CCK-33/39 were measured during the infusion of intraduodenal fat.
