Lucigenin is a chemiluminescent probe used to detect superoxide production and the presence of chloride.1,2 It can be used to detect superoxide production by enzymatic and cellular sources.1,3,4 It is a sensitive method that has been applied to the monitoring of superoxide production from xanthine oxidase, microsomal NADPH cytochrome reductase, and NADPH oxidases of phagocytes, endothelial cells, fibroblasts, and smooth muscle cells of blood vessel walls.3,5 However, it produces similar chemiluminescence signals in isolated aortic and cardiac tissues from wild-type and Nox1-Nox2-Nox4 triple knockout mice, suggesting that it is not selective for NADPH-based ROS production.6 It also reacts with hydrogen peroxide without generating free radical intermediates and has been used to detect lipid hydroperoxide in oils.7 Lucigenin is also used as a fluorescent chloride-sensitive indicator, with its fluorescence being quenched by chloride (ex/em = 455/505 nm, respectively).2,8,9 Lucigenin fluorescence is insensitive to phosphate, sulfate, and nitrate.2

Dithiothreitol-Lucigenin Chemiluminescent System for Ultrasensitive Dithiothreitol and Superoxide Dismutase Detection
Anal Chem 2022 Aug 9;94(31):11023-11029.PMID:35878317DOI:10.1021/acs.analchem.2c01690.
1,4-Dithiothreitol (DTT), a highly water-soluble and well-known reducing agent for preservation and regeneration of sulfhydryl groups in biomedical applications, has been developed as an efficient and stable coreactant of Lucigenin for the first time. DTT efficiently reacts with Lucigenin to generate intense chemiluminescence (CL), eliminating the need for external catalysts to facilitate the Lucigenin CL. The DTT-lucigenin CL is approximately 15-fold more intense when compared with the lucigenin-H2O2 classical system. Superoxide dismutase (SOD) remarkably quenches the DTT-lucigenin CL. Based on this phenomenon, a newly developed CL approach for the determination of SOD was proposed with a linear range of 0.01-1.5 μg/mL and a limit of detection of 2.2 ng/mL. Various factors affecting the CL emission of the DTT-lucigenin probe were studied and optimized. Plausible mechanistic pathways for the CL coreaction of Lucigenin with DTT were proposed and fully discussed. Our proposed method not only has the merit of being selective toward the target analytes but also eliminates the need for the complex synthesis of luminescent probes and facilitates the sensitive detection of SOD in human serum and cosmetics SOD raw material with satisfactory recoveries.
Luminol and Lucigenin as detectors for O2.-
Free Radic Biol Med 1993 Oct;15(4):447-51.PMID:8225026DOI:10.1016/0891-5849(93)90044-u.
Univalent oxidation of luminol and univalent reduction of Lucigenin must precede reaction with O2.- if that reaction is to lead to luminescence. The assumption that luminol or Lucigenin, per se, reacts with O2.- in a way leading to luminescence is incorrect, and leads to misinterpretation of results. The chemical reactions leading to the O2(.-)-dependent luminescences of luminol and of Lucigenin are discussed.
Free radicals and cell chemiluminescence
Biochemistry (Mosc) 2009 Dec;74(13):1545-66.PMID:20210708DOI:10.1134/s0006297909130082.
Application of chemiluminescence (CL) for study of free-radical reactions in human and animal cells and tissues is considered in this review. Historically, the study of intrinsic (ultraweak) luminescence gave place to the measurement of CL in the presence of chemical activators (CL probes) and physical activators (sensitizers) of luminescence, which made the method much more sensitive and specific. The methods of CL and EPR are direct methods of radical investigation, though the advantage of the CL method consists in the fact that CL intensity is directly proportional to a steady-state concentration of the radicals responsible for luminescence (first of all, lipid and oxygen radicals) irrespective the activity of these radicals. The mechanisms of CL reactions in the absence of activators and in the presence of luminol and Lucigenin are considered. Examples of various applications of the CL method in medical, biological, and clinical investigations are given including those for estimation of the phagocytic activity of cells, antioxidant activity, determination of toxicity, and other purposes.
[Chemiluminescent assay for biological substances using Lucigenin]
Yakugaku Zasshi 1997 Nov;117(10-11):864-74.PMID:9414596DOI:10.1248/yakushi1947.117.10-11_864.
The chemiluminescent reaction of Lucigenin with various biological substances has been studied. Chemiluminescence of Lucigenin is produced by the addition of either hydrogen peroxide or organic reducing compounds to Lucigenin in an alkaline solution. On the basis of these reaction, we have developed highly sensitive chemiluminescent methods for the detection of enzyme immunoassay, especially using alkaline phosphatase as a label enzyme, and also for HPLC of corticosteroids or p-nitrophenacyl esters of carboxylic acids. The detection limits of enzymes were 10(-19)-10(-20) mol per assay, corticosteroids and p-nitrophenacyl esters were 500 fmol per injection.
Development of lucigenin-N-hydroxyphthalimide chemiluminescence system and its application to sensitive detection of Co2
Spectrochim Acta A Mol Biomol Spectrosc 2022 Oct 15;279:121459.PMID:35700613DOI:10.1016/j.saa.2022.121459.
N-hydroxyphthalimide (NHPI) is an efficient organic catalyst and an important chemical raw material which can be used as an intermediate in organic synthesis of drugs and pesticides. In this study, NHPI has been used as a coreactant of Lucigenin chemiluminescence (CL) for the first time. The CL of the developed system is significantly enhanced in the presence of Co2+. Therefore, we developed a novel lucigenin-NHPI CL method coupled with flow injection analysis for the sensitive, precise, and selective determination of Co2+. The linear range of this method is 1-1000 nM, and the detection limit is 67 pM (S/N = 3). In addition, this method has a good selectivity for Co2+. It has been applied to the detection of Co2+ in lake water, and the standard recovery rate is 95.9-103.2%, indicating that the method is feasible.
