Description

technical field

[0001] The invention belongs to the field of biological enzyme application and biological technology, in particular to a single-channel enzyme activity automatic detection device. Background technique

[0002] Since the 1930s and 1940s, the detection of enzyme activity has been carried out by conventional colorimetric methods. This method has many shortcomings: (1) the results are greatly affected by the subjective factors of the operator, and the reproducibility is poor; (2) The analysis precision is low; (3) manual operation takes a long time, which is not conducive to the control of the enzymatic reaction process. Contents of the invention

[0003] In order to make up for the shortcomings of conventional enzyme activity detection methods, the present invention provides a single-channel enzyme activity automatic detection device, which is characterized in that the single-channel enzyme activity automatic detection device includes a sample injection part, ...
