2020-09-29 17:30 Enzyme labeling is a method used to place chemical markers on the molecules of substances in bioanalysis. Molecular markers allow the detection and tracking of molecules in substances during chemical analysis or testing. Different types of tags can be used for this type of biological tag. When one enzyme binds to another molecular chemistry, the process is called enzyme labeling. Enzyme markers include enzyme labeled antigen, enzyme labeled antibody and enzyme labeled SPA. The strategy of enzyme labeling is directly related to the success of immunoenzyme technology.
