摘要： The present invention is directed to methods and compositions for determining the presence, absence, and/or amounts of one or more membrane-associated analytes in a sample. In accordance with the invention, binding compounds derivatized with releasable molecular tags specifically bind to selected membrane-associated analytes, after which the molecular tags are released upon activation of cleavage moieties, or sensitizers, anchored in the same membrane as the membrane-associated analytes. The released molecular tags are then identified by their distinct separation and detection characteristics.

摘要： Ligands, such as antibodies, are screened for binding to cell surface moieties such as receptors. Multiple cell types and/or binding ligands can be screened simultaneously in multiplexed assays. The screening assays employ membrane-anchored electrophoretic probes for detection of binding of the ligand to the cell surface.

摘要： The invention is directed to a new class of biomarker in patient samples comprising dimers of ErbB cell surface membrane receptors. In one aspect, the invention includes a method of determining the status of a disease or healthful condition by correlating such condition to amounts of one or more dimers of ErbB cell surface membrane receptors measured directly in a patient sample, in particular a fixed tissue sample. In another aspect, the invention includes a method of determining a status of a cancer in a specimen from an individual by correlating measurements of amounts of one or more dimers of ErbB cell surface membrane receptors in cells of the specimen to such status, including presence or absence of a pre-cancerous state, presence or absence of a cancerous state, prognosis of a cancer, or responsiveness to treatment. Preferably, methods of the invention are implemented by using sets of binding compounds having releasable molecular tags that are specific for multiple components of one or more types of receptor dimers. After binding, molecular tags are released and separated from the assay mixture for analysis.

摘要： The invention provides methods and kits for detecting and/or measuring receptor homodimers on a cell surface membrane. In one aspect, the methods employ pairs of probes comprising binding compounds and a cleaving probe, such that at least one binding compound binds specifically to the same epitope of a membrane-bound analyte as the cleaving probe. The binding compound includes one or more molecular tags attached through a cleavable linkage, and the cleaving probe includes a cleavage-inducing moiety that can cleave the linkage when within a defined proximity thereto. Binding of the two probes to a homodimer of a cell surface molecules results in release of molecular tags from the binding compounds, providing a measure of formation of the homodimeric complex.

摘要： Methods are provided for detecting formation of oligomeric complexes of molecules on the surface of cell membranes. These methods employ pairs of tagged probes and cleaving probes, each of which binds specificly to a cell surface molecule. The tagged probe includes a molecular tag that is linked to a first binding compound through a cleavable linkage, and the cleaving probe includes a second binding agent and a cleavage-inducing moiety that can cleave the linkage when within a defined proximity thereto. Binding of the two probes to cell surface molecules that have formed an oligomeric complex results in release of the molecular tag from the binding compound, providing a measure of formation of the complex.
