  • Method of determining haptens, use of method and components useful in method
    Patent number: 5641690
    Abstract: A method is described for determining a hapten which method comprises (i) contacting the hapten with a binding partner of the hapten, whereby the hapten becomes bound to some of the binding partner, (ii) contacting the unbound binding partner with a secondary binding partner therefor, (iii) contacting the binding partner with an antibody which binds the binding partner which has bound thereto the hapten but which does not bind the binding partner which has bound thereto its secondary binding partner; and (iv) determining the amount of antibody bound to the binding partner. Kits for use in the method are also described.

  • Antibodies against the complex of a small molecule and its binding protein, their preparation and their use in diagnostic methods
    Patent number: 4828985
    Abstract: The invention involves polyclonal antibodies reactive with a complex of a hapten and its binding protein, wherein the antibodies are unreactive with the free hapten or free binding protein. The antibodies are useful in assays of the hapten or the binding protein.
