  • Publication number: 20120040337
    Abstract: This invention relates to a method to generate a signal used to detect the presence or quantity of a biomarker in a sample. The signal generating reaction is initiated when the biomarker under assay interacts with a specific binding partner. The interaction produces a structural change in the binding partner that is recognized by additional binding partners capable of generating a signal. The reaction produces a localized cluster of signaling molecules that can be detected above background. The signaling cluster is detectable within minutes when interrogated in a chamber of specific dimensions. The presence of the signaling clusters is a qualitative indication of the presence of the analyte, while the number of signaling clusters detected is a direct quantification of the number of biomarker molecules in the sample. The reaction can be formatted to detect proteins, nucleic acids, cells or other informative biomarkers.
