Summary for Patent: 4,410,634
Title: Method of passively adsorbing immuno-reactive haptens to solid phases
Abstract:The method comprises covalently binding an immuno-reactive to a selected macromolecular carrier and then contacting the resulting hapten-carrier conjugate at a selected concentration in a liquid phase with a selected solid phase until a desired amount of the hapten-carrier conjugate is adsorbed to the surface of the solid phase. Unbound hapten-carrier conjugate is then separated from the solid phase, and the solid phase containing the bound hapten-carrier conjugate is recovered for use in quantitative immunoassays and the like. The solid phase can be, for example, surfaces of a test tube or microtiter well or the like. The method is simple and inexpensive and permits hapten assays of improved sensitivity.
