Luminol-induced neutrophil chemiluminescence

Biochimica et Biophysica Acta (BBA) - General Subjects, 1980
Out studies suggest that luminol directly enhances the chemiluminescence of human neutrophils. We show that a significant peak in chemiluminescence production in a particle-free system occurs between 5 and 15 min following exposure of cells to micromolar concentrations of luminol.

Synthesis of photosensitive luminol releasing compound, luminol-O-2-nitrobenzylate

Journal of Photochemistry and Photobiology A: Chemistry, 2004
Abstract Luminol- O -2-nitrobenzylate ( 1 ), which releases luminol upon light irradiation at 366 nm and can measure light power, was developed. 1 has a 2-nitrobenzyl group at the carbonyl oxygen of luminol. The released luminol emitted light in the presence of NaOH and H 2 O 2 .

Luminol assay for superoxide dismutase

Analytical Biochemistry, 1981
Abstract Superoxide dismutase (EC 1.15.1.1) has been assayed by a method utilizing reduction in the chemiluminescence of luminol. This method avoids artifacts introduced in crude tissue preparations by the presence of nonsuperoxide sources of reduction of other substrates; luminol is specific for superoxide.

Luminol chemiluminescence: Chemistry, excitation, emitter

Journal of Bioluminescence and Chemiluminescence, 1990
AbstractThe mechanism of luminol chemiluminescence is a special case of nucleophilic addition to carbonyl compounds. The breakdown of the key intermediate, an alpha hydroxy hydroperoxide, produces a peracid ortho to an acyl diazene group. After intramolecular addition of the peracid, the energy from nitrogen expulsion is utilized in the formation of an

Luminol oxidation with chemiluminescence 6. Oxidation of luminol by xenon difluoride

Bulletin of the Academy of Sciences of the USSR Division of Chemical Science, 1979
1. Luminol undergoes a bimolecular, two-electron oxidation to diazaquinone in reacting with luminol at pH 9–13. 2. The hydrolysis of diazaquinone gives rise to the blue CL component, even in oxygenfree systems. 3. The green CL component is also observed in oxygen-free systems, arising from recombination of amino radicals ...
