  • Barbituric acid antigenic conjugates, their preparation, antibodies and use
    Patent number: 4036823
    Abstract: Antigenic barbituric acid conjugates are produced by coupling the hapten acid through its 3-position to an immunogenic carrier. The antigens thus produced can be used to raise antibodies in animals, the antibodies being specific to the barbituric acid hapten compound employed. The antibodies are useful in assaying for the barbituric acid hapten compounds.
    Type: Grant

    Inventor: James R. Soares
  • Phenethylamine antigenic conjugates, their preparation, antibodies, and use
    Patent number: 4016146
    Abstract: Antigenic phenethylamine conjugates are produced by blocking the amine of the phenethylamine hapten with a group, coupling of the phenethylamine to a carrier, and removal of the blocking group. Specific phenethylamines useful in this invention are amphetamine, epinephrine, and norepinephrine. The antigens thus produced can be used to raise antibodies in animal bodies, the antibodies being specific to the phenethylamine compound employed. In particular, this disclosure is directed to blocked phenethylamines for production of antigens and to a process for preparing the antigens.
