A series of 10-methyl-9-(phenoxycarbonyl)acridinium trifluoromethanesulfonates (XAEs), bearing substituents of various characteristics in the lateral benzene ring (2-halogen, 2,6-dihalogen, 2-trifluoromethyl, 2-nitro, 2-methoxy, 3-halogen and 4-halogen) were synthesized with high yields, identified and subjected to a physicochemical and theoretical investigation. The main task of the work was t...

The principles of chemiluminescence and its applications as diagnostic tool are reviewed. After an introduction to the theoretical aspects of luminescence and energy transfer, the different classes of chemiluminogenic labels including luminol, acridinium compounds, coelenterazine and analogues, dioxetanes, systems based on peroxyoxalic acid and their derivatives are described emphasizing the mo...

Identification of members of the Mycobacterium tuberculosis complex and the M. avium-M. intracellulare complex (MAC) directly from primary BACTEC cultures was evaluated by using acridinium-ester-labeled DNA probes (AccuProbe; GenProbe, Inc., San Diego, Calif.). In preliminary experiments, blood present in samples was found to interfere with the assay because of nonspecific chemiluminescence, wh...

Inununoassays based on chemilunlinescent acridinium salts are highlysensitive, robust, and simple (1) but have not been demonstrated in a microplate format because of the lack of suitable luminometers with “on-board” reagent injection systems necessary for quantifying rapidchemiluminescent reactions. We report our initial studies on a two-site immunochemiluminometric assay (IcMA) for thyrotropi...
