Versuchsvorschrift

For example, and not by way of limitation, 10 mg of benzoyl ecgonine in 5 ml tetrahydrofuran (“THF”) may be added to 1.1 equivalent N-hydroxysuccinimide (NHS) and 1.1 equivalent of Ethyl 3-(3-dimethylaminopropyl)-3-ethylcarbodiimide hydrochloride (EDC). The reaction mixture may be stirred at room temperature for about 30 min. The solvent may then be removed under reduced pressure and the resultant cocaine activated ester, cocaine-NHS (a cocaine pre-hapten), may be dissolved in 0.2 ml of DMF and mixed with 5 mg of carrier Self protein in 1 ml PBS. The mixture may then be stirred for about 3 hour at about 4 C.° to provide cocaine/Self protein conjugate. The foregoing amounts may be varied depending on the desired yield of conjugate. In preferred non-limiting embodiments, the carrier Self protein may be HSA or MSA or TSA.
