C07F 960 C07F 940
US Classification:
544244
Abstract:
The present invention encompasses a method for determining ligands in test samples comprising intermixing with the test sample a ligand analog-irreversible enzyme inhibitor conjugate and a binding protein bindable to the ligand and the ligand analog-irreversible enzyme inhibitor conjugate and wherein the amount of ligand analog-irreversible enzyme inhibitor conjugate bound by the binding protein is related to the amount of ligand in the test sample, said binding protein inactivating the irreversible enzyme inhibitor when bound to the ligand analog portion of the conjugate; intermixing an enzyme which is irreversibly inhibited by the ligand analog-irreversible enzyme inhibitor conjugate unbound by the binding protein; and intermixing substrate to the enzyme and monitoring the enzyme substrate reaction. The invention also includes ligand analog-irreversible enzyme inhibitor conjugates useful as reagents in practicing the method. Methods and reagents of the present are particularly useful in determining drugs, hormones, and the like in biological fluids.

Radioimmunoassay For Determining The Digoxin Content Of A Sample

Abbott Laboratories - North Chicago IL
International Classification:
G01N 3300 G21H 502 C07J 1900
US Classification:
424 15
Abstract:
A competitive radioimmunoassay for the measurement of digoxin in a serum sample in which the non-radioactive digoxin competes with a constant amount of a radioactively labeled digoxin tyramine analog comprising 3-O-(4-Hydroxyphenethylcarbamoyl) digoxigenin for binding cites on a limited amount of digoxin antibody. The percentage of the radioactively labeled digoxin which is bound to the antibody is inversely proportional to the concentration of digoxin in the serum sample. The concentration of digoxin in the serum is determined by the comparison with standards containing measured amounts of unlabeled digoxin.
