Suitability evaluation method for duodenal fluid sample as a sample for detection of component derived from pancreatic juice

摘要

A method for evaluating whether or not the duodenal fluid sample is suitable as a sample for detecting pancreatic juice derived components is provided for a duodenal fluid sample collected from an animal. (A) mixing a duodenal fluid sample with a chymotrypsin-specific substrate and measuring a degradation activity of the chymotrypsin specific substrate by the duodenal fluid sample, (b) mixing the duodenal fluid sample and a pepsin specific substrate Measuring the degradation activity of the pepsin specific substrate by the duodenal fluid sample; and (c) measuring the activity of degrading the chymotrypsin specific substrate of the duodenal fluid sample and the degradation of the pepsin specific substrate of the duodenal fluid sample And a step of evaluating whether or not the duodenal fluid sample is suitable as a sample for detection of a component derived from pancreatic juice based on the activity, as a sample for detecting component derived from pancreatic juice of a duodenal fluid sample.
