Abstract
The present invention provides hapten derivatives that are useful for the preparation of antigens, antibodies and reagents having superior performance characteristics for use in immunoassays for the detection of LSD and nor-LSD. In the present invention the LSD nucleus is derivatized out of the indole nitrogen to form an aminoalkyl derivative. Derivatives have also been synthesized out of the piperidine nitrogen of the LSD nucleus. The resulting haptens can then be further modified at these functionalized positions for linking to appropriate antigenic or labelling groups to provide reagents for LSD immunoassays having excellent sensitivity and selectivity for both LSD and nor-LSD.
