Measured value Ratio to control (%)
Animal species Others
Indication of the result Remaining releasing activities of 2-chloro-4-nitorphenol from Gal-Glc-CNP by a-amylase in the presence of test samples.
Target diseases of assay Digestive system
Assay level Cell-free
Protocol of assay 1. MES buffer (1000 ml) was used as a reference.
2. Add MES buffer, a-amylase, and a sample in a cell, and incubate it at 37˚C for 10 min.
3. Add the substrate solution into the cell and monitor the change in absorvance at 405 nm.
4. Calculate the remaining activitiy for each sample.
