PROXIMITY-MEDIATED ASSAYS FOR DETECTING ONCOGENIC FUSION PROTEINS

摘要

The present invention provides antibody-based arrays for detecting the activation state and/or total amount of one or a plurality of oncogenic fusion proteins in a biological sample such as whole blood or tumor tissue and methods of use thereof. In certain instances, the activation state and/or total amount of oncogenic fusion protein(s) present in a sample can be measured in combination with one or a plurality of signal transduction molecules. The compositions and methods of the present invention have the advantages of specificity associated with enzyme-linked immunosorbent assays, sensitivity associated with signal amplification, and high-throughput multiplexing associated with microarrays.
