Description
Technical field
The present invention relates to technical field of analysis and detection more particularly to a kind of chemiluminescence intensifier and chemiluminescence immunoassay to examine
Test agent box.
Background technique
Chemiluminescence immune assay (Chemiluminescence Immunoassay, CLIA) is by chemiluminescence or life
Object luminescence system is combined with immune response, for detecting a kind of novel markings immunoassay of trace antigen or antibody.
Chemiluminescence immune assay is the immunoassay technology of most mainstream in current world wide, have high sensitivity, detection range it is wide,
Reaction time is short, full automatic working, favorable reproducibility, it is pollution-free the advantages that, be after putting immune technology, enzyme immune technology, fluorescence immunoassay skill
A kind of Micrometry of the hypersensitivity to grow up after art.Chemiluminescent principle is when ground state molecule absorptionization
The energy jump discharged in reaction is learned to excitation state, the molecule in excitation state generates when returning to ground state in the form of light radiation
