Radioactive reagents have been gradually replaced by nonisotopic reagents for some tasks in molecular biology. Concern over laboratory safety and the economic and environmental aspects of radioactive waste disposal have been key factors in this change. Generally, the new nonisotopic systems have improved in terms of analytical sensitivity and the time ...

The chemiluminescence of riboflavin
Archives of Biochemistry and Biophysics, 1953Abstract 1. 1. It has been found that the oxidation of riboflavin with peroxide produces light of approximately the same color as the fluorescence of riboflavin. 2. 2. Data concerning the temperature dependence of the reaction have been presented. 3. 3. Optimal luminescence without added metallic activators occurs around pH 7–8. 4. 4.

Electrogenerated Chemiluminescence
Annual Review of Analytical Chemistry, 2009In electrogenerated chemiluminescence, also known as electrochemiluminescence (ECL), electrochemically generated intermediates undergo a highly exergonic reaction to produce an electronically excited state that then emits light. These electron-transfer reactions are sufficiently exergonic to allow the excited states of luminophores, including ...

Chemiluminescence and immunoassays
Journal of Pharmaceutical and Biomedical Analysis, 1994The principles of chemiluminescence and the application of chemiluminescent labels and substrates in immunoassays are reviewed. Various immunoassay formats and all known classes of chemiluminescent molecules, including 1,2-dioxetanes, luminol and derivatives, acridinium esters, oxalate esters and firefly luciferins are described as well as the many ...

Novel chemiluminescence system with calcein as chemiluminescent reagent
Luminescence, 2007AbstractChemiluminescence (CL) was observed when calcein reacted with potassium ferricyanide. Several metal ions and organic compounds could enhance this CL signal. The possible mechanisms for the CL reactions and the enhancement effect were investigated via studies of the CL kinetic characteristics, the CL spectra of some related reactions, the UV ...

Chemiluminescence of cereal products. II. Chemiluminescence spectra
Journal of Bioluminescence and Chemiluminescence, 1998Spectra of ultraweak chemiluminescence (CL) accompanying auto-oxidation and hydration of cereal products have been measured using single photon counting and cut-off filters. The spectra cover the 380-880 nm spectral range with maxima centred around 600 nm.

CHEMILUMINESCENCE IN SOLUTIONS
Soviet Physics Uspekhi, 1966Abstract : The purpose of the work is to give a synopsis of the present condition of research of the mechanism of chemiluminescence and to discuss future developments in this field of physical chemistry. The synopsis is concerned with liquid-phase systems, but the other aspects of chemiluminescence are briefly touched upon in it.
