    摘要: Optical indicator chalcogen (selenide or sulfide) compounds responsive to oxidants, e.g., hydrogen peroxide, and methods for preparing and using such indicators. Upon oxidation the resulting intermediate undergoes spontaneous elimination of the chalcogen residue to yield a signal compound which provides an optical signal such as fluorescence. Preferred fluorogenic indicator compounds are 3-chalcogen-3,4-dihydrocoumarin derivatives and 3-chalcogen-3,4-dihydro-2-quinolone derivatives. Such indicator compounds provide highly fluorescent products upon oxidation by hydrogen peroxide and are useful in analytical systems which generate hydrogen peroxide in response to the analyte under determination.

    摘要: Disopyramide immunogens, antibodies prepared therefrom, labeled conjugates, synthetic intermediates, and the use of such antibodies and labeled conjugates in immunoassays for determining disopyramide. The immunogens comprise disopyramide coupled by an ether linkage at a selected singular position on its phenyl ring to an immunogenic carrier material. Likewise, the labeled conjugates and synthetic intermediates are phenyl ether derivatives of disopyramide or precursors thereof. The antibody and labeled conjugates are particularly useful in homogeneous nonradioisotopic immunoassays for measuring disopyramide in biological fluids such as serum.
