An immunogen useful in eliciting antibodies for determining the presence or amount of methadone in a test sample, comprising the structure:
wherein:
R and R' represent a spacer group consisting of from 0 to 15 carbon atoms and heteroatoms, including not more than six heteroatoms, arranged in a straight or branched chain, saturated or unsaturated, with the proviso that not more than two heteroatoms may be linked in sequence and, in the case of R, that branchings may occur only on carbon atoms;
x is 0 or 1;
M is a linking group selected from C=O, -NH-, O-C=O, N-C=O, and N-C=S; and
Q is an immunogenic carrier. Haptens used to make the immunogens are also disclosed.
一种用于激发抗体以确定测试样品中是否存在美沙酮或其含量的免疫原,包括以下结构:
其中
R和R'代表由0至15个碳原子和杂原子(包括不超过6个杂原子)组成的间隔基团,排列成饱和或不饱和的直链或支链,但不得有两个以上的杂原子依次相连,在R的情况下,只能在碳原子上发生分支;
x 为 0 或 1;
M 是一个连接基团,选自 C=O、-NH-、O-C=O、N-C=O 和 N-C=S;以及
Q 是免疫原载体。用于制造免疫原的巯基也已公开。

A fluorescence polarization immunoassay for detecting the presence of methadone in a test sample is provided, based upon competition between methadone and a fluorescently labeled tracer for the binding sites on an antibody specific for methadone. The concentration of methadone 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 methadone in the sample. Tracers used as reagents and immunogens used to raise antibodies for use as reagents are also disclosed.
