The characteristics of the luminol-amplified chemiluminescence (CL) induced in mononuclear phagocytes interacting with PMA, FMLP or ionomycin were determined. Azide reduced the CL activity by more than 80%. while superoxide dismutase and catalase had minor effect on the monocyte CL response. The sen

β¦ Synopsis
The granulocyte luminol-dependent chemiluminescence (CL) reaction is linked to the enzyme myeloperoxidase reacting with products of the respiratory burst activation. The results presented in this paper, show that the light generated in granulocytes originate both from intracellular and extracellular reactions; however, depending on the stimulus used the one or the other will dominate the activity measured. Furthermore, lysosomal fusion is proposed to be required for the intracellular CL reaction.

To assess the effect of sulphite on the oxidative metabolism of human neutrophils, chemiluminescence (CL) measurements were performed using lucigenin and luminol as chemiluminigenic probes. Lucigenin-dependent CL was used for measuring superoxide anion (0;) production, and luminol-dependent CL was u
Chemiluminescence produced by the catalytic effect of iron(B)-oxime complexes on the oxidation of luminol by hydrogen peroxide was studied. This is a very fast chemiluminescence reaction and the emission spectrum is similar to that of peroxidase-catalysed chemiluminescence. Different kinds of iron(B
