Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of enzyme-labeled detection equipment, in particular to an enzyme-labeled instrument for laboratory use. Background Art
[0002] The microplate reader is a commonly used detection instrument in analytical biology for measuring the rate and activity of enzymatic reactions. It can determine the concentration or activity of a specific enzyme in a target sample by detecting parameters such as reaction depth, color change, and luminescence. Its working principle is to add the target sample to a reaction system containing a substrate, and use the specific catalytic effect of the enzyme to cause a specific reaction change in the substrate. Then, the activity level of the enzyme is determined by measuring the changes in optical signals generated by the reaction, such as absorbance, luminescence intensity, etc.
[0003] During use of existing laboratory ELISA instruments, the sample plate needs to be placed in a positioning groove and moved into the detector for detection. However, the inventors found that when the sample plate is placed in the positioning groove, the sample plate is prone to tilt, resulting in inaccurate detection. Therefore, we propose a laboratory ELISA instrument. Utility Model Content
