Theophylline immunogens, antibodies prepared therefrom, labeled theophylline conjugates, synthetic intermediates, and the use of such antibodies and labeled conjugates in immonoassays for determining theophylline are disclosed. The immunogens comprise theophylline coupled at its 9-position to an immunogenic carrier material. Likewise, the labeled conjugates and synthetic intermediates are 9-position derivatives of theophylline or synthetic precursors thereof. The antibody and labeled reagents are particularly useful in homogeneous nonradioisotopic immunoassays for measuring theophylline in biological fluids such as serum.
