Immunochemical determination of two trypsins in human duodenal juice.
An application of electroimmunoassay to the separate determination of anionic and cationic trypsin in human duodenal juice is presented. The proportions of anionic to cationic immunoactive trypsin in duodenal juice from a group of children averaged 20 : 80. The ratio of immunoactive to esterolytically (BAPNA) active trypsin averaged 1.6 : 1, indicating the presence of inactive forms of trypsin in duodenal juice.
