Abstract: The present invention provides methods, compositions and kits for the characterization of cellular pathways in cells containing genetic alterations.

Abstract: Methods for determining a model that can characterize and distinguish normal cell from a diseased cell and methods for determining health or health-risk status of an individual based on a normal/health cell reference population of cells are described.

Abstract: In one embodiment, one or more processor-readable media storing code representing instructions that when executed by one or more processors cause the one or more processors to receive a set of parameter values defining a boundary within a data space associated with a dataset. The dataset can represent signaling related to a test substance. A first metric can be defined based on a first portion of the dataset associated with a first region defined by the boundary. A second metric can be defined based on a second portion of the dataset associated with a second region defined by the boundary after the boundary is modified. The second region can be different than the first region.

Abstract: An embodiment of the present invention is useful for identifying tumor cells in bladder cancer washes, pleural effusions, biliary tumor cells and circulating tumor cells in whole blood. Subsequent analysis may identify therapeutic treatments based on a single cell analysis of activatable elements in cell signaling pathways. This analysis can be useful for diagnosis, prognosis, therapy selection and monitoring of solid tumor diseases.

Abstract: A method is disclosed in which control processes are used to maintain consistency across a research or diagnostic series of steps. Some embodiments of the processes include the use of fresh or lyophilized cell lines, beads, surface or other markers. The use of quality control processes is intended to monitor data from the underlying methods in order to detect unacceptable variations and to allow for exclusion or normalization. Overlapping control processes allows for tighter control and for redundancy in the monitoring.

Abstract: This invention is directed to methods and compositions for diagnosis, prognosis and for determining methods of treatment. The physiological status of a cell present in a sample (e.g. clinical sample) can be used in diagnosis or prognosis of a condition (e.g. Chronic Lymphocytic Leukemia), in patient selection for therapy, to monitor treatment and to modify or optimize therapeutic regimens.

Abstract: The invention provides methods, kits, devices and compositions for detecting one or more target analytes. In some embodiments, the invention provides binding elements and labeling elements capable of being joined through a plurality of joining elements.
