摘要:
Phenobarbital conjugates for use as enzyme inhibitors having the formula: ##STR1## wherein Z is a biologically compatible counter ion, n and m is an integer from 2 to 6 and R and R.sub.1 are each lower alkyl.
摘要:
The present disclosure relates to a novel class of substituted theophylline salts useful as reagents in an irreversible enzyme inhibitor immunoassay for theophylline. The use of such reagents increases the sensitivity of the theophylline assay.
摘要:
A fluorescence polarization immunoassay (FPIA) for detecting the presence of one or more amphetamine-class analytes in a test sample is provided. The immunoassay uses competition between the analyte and a fluorescently labeled tracer for the binding site on an antibody specific for phenethylamine derivatives. The concentration of amphetamine-class analyte in the sample determines the amount of tracer that binds to the antibody. The amount of tracer/antibody complex formed can be quantitatively measured and is inversely proportional to the quantity of analyte in the test sample. The invention relates to tracers, to immunogens used to elicit antibodies for use as assay reagents, and to assay kits incorporating these tracers and assay reagents.
