Enhanced chemiluminescence (ECL) is a common technique for a variety of detection assays in biology. A horseradish peroxidase enzyme (HRP) is tethered to an antibody that specifically recognizes the molecule of interest.
Electrochemiluminescence or electrogenerated chemiluminescence (ECL) is a kind of luminescence produced during electrochemical reactions in solutions. In electrogenerated chemiluminescence, electrochemically generated intermediates undergo a highly exergonic reaction to produce an electronically excited state that then emits light upon relaxation to a lower-level state.
Chemiluminescent immunoassay (CLIA) is a type of immunoassay employing chemiluminescence. [1] [2] See also. Enzyme-linked immunosorbent assay (ELISA) References
An immunoassay (IA) is a biochemical test that measures the presence or concentration of a macromolecule or a small molecule in a solution through the use of an antibody (usually) or an antigen (sometimes).
Eclox ECL is a broadband enhanced chemiluminescence (ECL) assay that can be used to qualitatively assess a water sample to determine whether it has been contaminated. ECL reactions are used in a number of clinical and analytical applications and are based upon the oxidation of luminol in the presence of the enzyme horseradish peroxidase (HRP), an oxygen source, and an enhancer such as 4 ...

Immunofluorescence or immunoperoxidase assays are commonly used to detect whether a virus is present in a tissue sample. These tests are based on the principle that if the tissue is infected with a virus, an antibody specific to that virus will be able to bind to it.
Horseradish peroxidase is a 44,173.9-dalton glycoprotein with six lysine residues which can be conjugated to a labeled molecule. It produces a coloured, fluorimetric [6] or luminescent derivative of the labeled molecule when incubated with a proper substrate, allowing it to be detected and quantified.
