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： Methods are provided for detecting the formation of complexes of molecules, especially proteins, in a sample, such as a cell or tissue lysate. In one aspect, a cleaving probe specific for a first protein in a complex and one or more binding compounds specific for one or more second proteins in a complex are provided. Upon binding, the cleaving probe is induced to generate an active species, such as singlet oxygen, that cleaves molecular tags attached to the binding compounds only in the local region of the cleaving probe. The released molecular tags are separated from the assay mixture and from one another to provide a readout that is related to the number and types of proteins present in the complex.

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： A method of determining the status of a disease or healthful condition by correlating such condition to amounts of one or more heterodimers of ErbB, or Her, cell surface membrane receptors measured directly in a patient sample is described. 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 heterodimers 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 a method for determining the activation status of receptor tyrosine kinase (RTK) pathways in either cell samples or patient samples by measuring receptor dimerization and relative amounts of protein-protein complexes or activated effector proteins that are characteristic of an RTK pathway. The invention also provides a method of using such status information to select patients responsive to pathway-specific drugs, and more particularly, to methods for measuring ErbB receptors and receptor complexes and using such information to select patients responsive to ErbB pathway-specific drugs. 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 complexes formed in RTK activation. After binding, molecular tags are released and separated from the assay mixture for analysis.
