[Determination of antibodies to opiate receptors by latex agglutination and immunoenzyme analysis].

Adsorption ability of few kinds of latex covered by synthetic peptide fragments of mu- and delta-opiate receptors (OR) is investigated. The levels of autoantibodies to opiate receptors fragments in the blood serum of patients with drug abuse are detected by latex agglutination and ELISA. The patients with drug abuse demonstrated positive latex agglutination reaction for level specific antibodies from 10.
