    摘要： An immunoassay method and analytical elements for detecting carbamazepine drugs, for example, in body fluids, is described. The immunoassay method comprises:(A) contacting a liquid sample, containing carbamazepine, with a labeled carbamazepine analogue in the presence of antibodies for carbamazepine under conditions that promote the formation of carbamazepine/antibody immunocomplexes; and(B) determining the quantity of the drug in the liquid by measuring bound or unbound labeled drug analogue; characterized in that the labeled carbamazepine comprises:(1) a label, of the type used in immunoassays, having an amine or sulfhydryl group;(2) a carbamazepine nucleus; and(3) a linking chain linking the carboxamide group of the carbamazepine nucleus to the label, said linking chain having about 4 to about 40 atoms consisting of:(a) alkylene groups; and(b) heterocyclic ring groups, each group being joined into the linking group through chemical groups selected from(a) esters,(b) amides,(c) heteroatoms selected from --O--, --S--, and --NR--; wherein each R independently represents hydrogen or C.sub.1 to C.sub.6 alkyl; and(d) carbonyl groups.The elements of the invention are preferably dry, thin film analytical elements comprising a labeled carbamazepine analogue as described.

    摘要： A biologically active reagent is prepared by reacting a biologically active substance covalently to a polymeric particle having pendant aldehyde groups. Such groups are provided by a polymerizable monomer represented by the structure: ##STR1## wherein Ar is arylene, R and R.sup.1 are independently hydrogen, halo or lower alkyl, R.sup.2 and R.sup.3 are independently alkylene of 1 to 4 carbon atoms in the chain, R.sup.4 is arylene, m is 0 or 1, and n is an integer of 1 to 4. These reagents can be used in a variety of specific binding and affinity purification methods, and in both solution assays and dry analytical elements.
