Generation and utilization of anti-drug monoclonal antibodies for screening of 36 drug users by dot-ELISA.

ABSTRACT

In this study, we prepared monoclonal antibodies against morphine, methadone, babital, methamphetamine, and phencyclidine, then developed a dot-ELISA method by such antibodies to test their efficacy in clinical application and the screening of urine samples. It was found that there were 36 narcotics-positive drug users, including 28 morphine positive, six methamphetamine positive, and two positive for both. All the results were confirmed by commercial drug testing kits.
