    摘要: Immunoassay methods and reagents for the specific quantification of imipramine or desipramine in a test sample are disclosed. The measurement of imipramine or desipramine is accomplished in a specific immunoassay employing antibodies prepared with imipramine or desipramine derivatives of formula (III), wherein P is an immunogenic carrier material, X is two heteroatoms, Y is a linking group comprising from 1 to 6 carbon atoms and P is an immunogenic carrier material, and wherein for imipramine, R is CH3, and for desipramine, R is H. The present invention also describes the synthesis of unique labeled reagents of the structure of formula (IV), wherein Z is a linking group comprising 1 to 4 carbon atoms and 0 to 2 heteroatoms and Q is a detectable moiety, preferably fluorescein or a fluorescein derivative, and wherein for imipramine, R1 is CH3, and for desipramine, R1 is H.

    摘要: A method and device for testing for the presence of substances such as drugs in body fluids while simultaneously positively identifying the test subject. The device comprises an absorbent pad and a membrane mounted to the absorbent pad containing a plurality of separated areas provided with different immobilized ligand having a specific receptor site for capture or rejection of specific antigens produced by different predetermined drugs. The method of testing comprises the steps of: (a) obtaining a quantity of body fluid in a container, (b) adding an antibody to the body fluid to form a mixed solution, (c) placing the mixed solution on a membrane and absorbent pad device and immobilized ligands, (d) covering the finger with a thin film of labelled antibody and (e) placing the finger on the membrane containing immobilized ligand specifically selected to bind to labelled antibody presenting the fingerprint of the test subject, the presence or absense of substances being tested for in the body fluid so that solution is deposited from the finger on the membrane indicating presence or absence of the substance.
