Reagents for use in binding assays, particularly immuno-assays, to determine diphenylhydantoin and for preparing reagents employed in such assays, including .beta.-galactosyl-umbelliferone-diphenylhydantoin conjugates, diphenylhydantoin immunogens, and N.sup.1, N.sup.3 and .omicron.-phenyl derivatives of diphenylhydantoin for preparing same. N.sup.1 and N.sup.3 -.omega.-aminoalkyl and .omicron.-(.omega.-aminoalkoxy)-phenyl derivatives are prepared and coupled by amide linkage to a .beta.-galactosyl-umbelliferone derivative to form labeled conjugates useful in homogeneous or heterogeneous binding assays. N.sup.1 and N.sup.3 -.omega.-carboxyalkyl and .omicron.-(.omega.-carboxyalkoxy)-phenyl derivatives are prepared and coupled by amide linkage to an immunogenic polyamino acid to form immunogen conjugates against which diphenylhydantoin-specific antibodies can be raised.
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:
Immunogens for preparing antibodies against the drug lidocaine and related compounds, labeled conjugates, synthetic intermediates, and the use of such antibodies and labeled conjugates in immunoassays for determining lidocaine and such related compounds. The immunogens comprise lidocaine or an analog thereof coupled through one of the aromatic methyl groups to a conventional immunogenic carrier. The antibodies and labeled conjugates are particularly useful in homogeneous nonradioisotopic immunoassays for measuring lidocaine or its analogs in biological fluids such as serum.

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.
