Abstract
Novel carboxyalkylated disopyramides (NORPACE.RTM.) are provided as precursors for conjugating proteins, either antigenic for the preparation of antibodies or enzymatic for the preparation of enzyme conjugates, which antibodies and enzyme conjugates find use as reagents in immunoassays. The combination of antibodies and enzyme conjugates provide for sensitive, accurate, rapid assays for disopyramide without interference from closely analogous compounds, such as methadone or disopyramides metabolites.
