Patent number: 6573109Abstract: The present invention relates to a membrane for use in detecting the presence of an analyte. The membrane comprises an array of closely packed self-assembling amphiphilic molecules and a plurality of first and second receptor molecules, the first receptor molecules being reactive with one site on the analyte and second receptor molecules being reactive with another site on the analyte. The first receptor molecules are prevented from lateral diffusion within the membrane whilst the second receptor molecules are free to diffuse laterally within the membrane. The membrane is characterized in that the ratio of first receptor molecules to second receptor molecules is 10:1 or greater.Type: GrantFiled: October 10, 1995Date of Patent: June 3, 2003Assignees: Australian Membrane and Biotechnology Research Institute, The University of SydneyInventors: Bruce A.

Patent number: 5874316Abstract: The present invention provides a membrane the conductivity of which is dependent on the presence or absence of an analyte. The membrane comprises a closely packed array of self-assembling amphiphilic molecules and two ionophore components. A receptor molecule reactive with the analyte is provided on one of the ionophore components. The binding of the analyte to the receptor molecule causes a change in the relationship between the ionophore components such that the flow of ion across the membrane is prevented or allowed. The ionophore components are preferably selected from the group consisting of amphotericin B, gramicidin A monomers and combinations thereof, with gramicidin A monomers being particularly preferred. The present invention also provides a membrane including receptors directed against the Fc region of antibodies. These receptors are preferably derived from polyclonal antibodies.Type: GrantFiled: October 30, 1996Date of Patent: February 23, 1999Assignee: Australian Membrane Biotechnology Research InstituteInventors: Bruce A.
