  • Applications of acridinium compounds and derivatives in homogeneous assays
    Patent number: 7875467
    Abstract: Chemiluminescent acridinium compounds are used in homogeneous assays to determine the concentration of an analyte in a sample without strong acid or strong base treatment. The chemiluminescent acridinium compounds include acridinium esters with electron donating functional groups at the C2 and/or C7 position on the acridinium nucleus to inhibit pseudo-base formation, or acridinium sulfonamides with or without electron donating functional groups at the C2 and/or C7 position on the acridinium nucleus.
    Type: Grant
    Filed: November 21, 2007
    Date of Patent: January 25, 2011
    Assignee: Siemens Healthcare Diagnostics Inc.
    Inventors: Anand A. Natrajan, Todd Sells, Hartmut Schroeder, Guohan Yang, David Sharpe, Qingping Jiang, Hana Lukinsky, Say-Jong Law
