AN IMMUNO SENSOR FOR SPECIFIC PROTEIN

Abstract

Abstract An immuno sensor for determining specific protein has been developed. The measuring system is characterized by the potentiometric determination of potential difference across an antigenbinding membrane. A lipid antigen containing cardiolipin, phosphatidyl choline, and cholesterol was immobilized to an acetylcellulose membrane. The membrane-bound antigen retained the immunochemical reactivity to Wassermann antibody. The assymmetric membrane potential developed was dependent on the concentration of the antibody.
