Abstract
Novel hapten compositions consisting of 4-[4-[2-(aminopropyl)]phenyl]butanoic acid and its N-methyl derivative are useful in preparing immunogens which can be respectively employed in the elicitation of antibodies selective to amphetamine and methamphetamine. These antibodies can be used as reagents in immunoassays for these two compounds.
Claims3
An antibody specific to amphetamine prepared by inoculating a host animal with an immunogen of the formula ##STR8## which is covalently bonded through the carboxyl group to an immunogenic carrier material, where R.sub.1 is hydrogen and R.sub.2 is hydrogen, and thereafter collecting serum from said host animal.
An antibody specific to methamphetamine prepared by inoculating a host animal with an immunogen of the formula ##STR9## which is covalently bonded through the carboxyl group to an immunogenic carrier material, where R.sub.1 is methyl and R.sup.2 is hydrogen and thereafter collecting serum from said host animal.
