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 the Formula III: ##STR1## 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 CH.sub.3, and for desipramine, R is H. The present invention also describes the synthesis of unique labeled reagents of the structure of the Formula IV: ##STR2## 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, R.sub.1 is CH.sub.3, and for desipramine, R.sub.1 is H.
本发明公开了一种用于特定定量检测测试样品中丙咪嗪或去甲丙咪嗪的免疫测定方法和试剂。通过使用用丙咪嗪或去甲丙咪嗪衍生物制备的抗体进行特定免疫测定,可以测量丙咪嗪或去甲丙咪嗪。其中衍生物的结构式为III:##STR1## 其中P为免疫原性载体材料,X为两个杂原子,Y为含有1到6个碳原子的连接基,P为免疫原性载体材料,对于丙咪嗪,R为CH.sub.3,对于去甲丙咪嗪,R为H。本发明还描述了结构式IV的独特标记试剂的合成:##STR2## 其中Z为含有1到4个碳原子和0到2个杂原子的连接基,Q为可检测的基团,优选为荧光素或荧光素衍生物,对于丙咪嗪,R.sub.1为CH.sub.3,对于去甲丙咪嗪,R.sub.1为H。
