摘要:
The invention provides haptens, immunogens comprising such haptens coupled to an antigenicity-conferring carrier material, conjugates comprising such haptens bonded to a labelling agent as well as, antibodies raised against such immunogens and capable of binding with leucomalachite green and malachite green.
摘要:
The invention provides a method and kit for detecting and determining tramadol and its major metabolites N-demethyltramadol and O-demethyltramadol using novel conjugates, immunogens and antibodies derived from N-derivatised and O-derivatised tramadol.
摘要:
The present invention describes the first immunoassay methods and kits for detecting or determining salvinorin A, its analogues and metabolites. Also described are antibodies for use in the immunoassay methods and kits for the detection and / or determination of salvinorin A, its analogues and metabolites..
摘要:
The present invention relates to a method for preparing haptens of formulae I and II that are useful in the preparation of immunogens, antibodies and conjugates, for use in competitive immunoassays for the detection of ractopamine, isoxsuprine and ritodrine. The haptens are prepared by reacting a phenylethanolamine derivative of formula D with a phenylalkylcarbonyl derivative of formula E:
in which, in formula I, Z 1 is a crosslinker and Z 2 is H and, in formula II, Z 1 is H and Z 2 is a crosslinker.
