  • Dielectric spectroscopy assays for screening of ion channel ligands
    Patent number: 8421484
    Abstract: A method for measuring membrane potential using dielectric spectroscopy is described. A new theoretical model allows for the determination of membrane potential from low-frequency impedance measurements to provide a non-evasive method which is both rapid and inexpensive.
    Type: Grant
    Filed: July 30, 2008
    Date of Patent: April 16, 2013
    Assignees: Purdue Pharma L.P., New Jersey Institute of Technology
    Inventors: Camelia Prodan, Victor I. Ilyin, Donald J. Kyle, Kevin Carlin, Gang Wu
