Methods Of Assessing Protein Interactions Between Cells

Abstract

Provided are methods of detecting and quantitatively measuring protein-protein interactions between proteins present on the surface of different cells using a sensitive antibody based assay. Antibodies specific for each target protein are either directly labeled, or are detected by labeled secondary antibodies. The antibodies are labeled with detectable tags that are releasable when the target proteins are within proximity to each other. Also provided are methods for facilitating diagnosis, prognosis, and treatment of cancer using this assay to detect protein-protein interactions between target proteins of interest. Methods of screening test agents that impact the protein-protein interaction are also provided.
