The present invention provides a hapten derivatized with a monofunctional or a bifunctional crosslinker, either at the nitrogen of the 8β-carboxamide or at N-6, of 2-oxo-3-hydroxy-LSD.
The present invention also provides an immunogen comprising the aforementioned hapten, coupled to an antigenicity-conferring carrier material, as well as, conjugates comprising the aforementioned hapten covalently bonded to a detectable labelling agent. In addition, the present invention concerns antibodies raised against the aforementioned immunogens.
Finally, the present invention relates to methods and kits for detecting or determining LSD metabolites [2-oxo-3-hydroxy-LSD and N-desmethyl-LSD (nor-LSD)] in biological fluids.
The antibodies of the present invention have broad specificity towards each of 2-oxo-3-hydroxy-LSD and nor-LSD.
本发明提供了一种用单官能团或双官能团交联剂衍生化的合价蛋白,交联剂可以是 2-氧代-3-羟基-LSD的 8β-甲酰胺的氮或 N-6。
本发明还提供了一种免疫原,该免疫原包括与抗原性增强载体材料偶联的上述合体,以及包括与可检测标记剂共价键合的上述合体的共轭物。此外,本发明还涉及针对上述免疫原的抗体。
最后,本发明涉及检测或确定生物液体中 LSD 代谢物[2-氧代-3-羟基-LSD 和 N-去甲基-LSD(nor-LSD)]的方法和试剂盒。
本发明的抗体对 2-oxo-3-hydroxy-LSD 和 nor-LSD 都具有广泛的特异性。
