The invention provides a method for determining the onset and / or progression of ALS in an animal. The method comprises (a) obtaining a sample from the animal, (b) analyzing the proteins in the sample by mass spectroscopy, and (c) determining a mass spectral profile for the sample. The invention also provides isolated protein biomarkers of ALS.

The inventors have discovered a collection of proteinaceous biomarkers (“AD biomarkers) which can be measured in peripheral biological fluid samples to aid in the diagnosis of neurodegenerative disorders, particularly Alzheimer's disease and mild cognitive impairment (MCI). The invention further provides methods of identifying candidate agents for the treatment of Alzheimer's disease by testing prospective agents for activity in modulating AD biomarker levels.

A theranostics technique for describing signaling pathway activity within a cellular or tissue sample may include analyzing a cellular sample to obtain sample quantitative values for a series of target protein modification levels reflected in a set of a plurality of protein biomarkers in the sample. The sample quantitative values may be compared to reference quantitative values for the same series of protein modification levels. The reference quantitative values may be statistically processed from a plurality of comparable samples. The sample quantitative values may be displayed in relation to the reference quantitative values in a way that may suggest a specific course of treatment.

Cassette (50) performs assays, e.g. multiplexed protein biomarker assays. Wide, bubble-free, slow flows are produced from liquids stored on cassette (50), flowing over wide array (20) of ligand receptors on a capture surface. Flows of Reynolds Number less than about 1, preferably 1×10−1 to 5×10−3, are heated in region (34) preceding and including bubble removal system (128). Analyte is introduced through compressed septum (32). External actuations of displacement pumps (30, 37) and valves (137 A, B, and C) produce flows in response to flow-front optical sensors (150, 152). Elastic sheet provides pump and valve diaphragms and resilient expansion of mixing volume (131). Break-away cover portions are pistons. Heating is by conduction through cassette from external contact heater. Planar cassette body, when tilted from horizontal, enables upward flow from pumped storage (134, 135) to reaction (133) to waste (139), with buoyancy bubble removal before reaction. Reading of fluorescence is by external reader, employing calibration, control and reference features on capture surface. Extensive set of calibration features of differing intensities enables self-calibration.

A method, kit and device for diagnosing Kawasaki Disease are provided. The invention provides detecting an expression level of at least two Kawasaki Disease diagnostic biomarkers in a biological sample from a patient with a capture agent and diagnosing the patient as having Kawasaki Disease when the expression levels of the at least two diagnostic biomarkers in the patient biological sample are higher than the normal expression levels of the same biomarkers in a biological sample from a control subject. The first Kawasaki Disease diagnostic biomarker disclosed in the present invention is a cardiomyocyte biomarker, and the second Kawasaki Disease diagnostic biomarker is an inflammatory biomarker. The invention further provides detecting an expression level of a third biomarker, interferon type-I biomarker, in the patient biological sample with a capture agent and diagnosing the patient as having Kawasaki Disease when the expression level of interferon type-I biomarker is lower than the expression level in a control subject.

The inventors have discovered sets of proteinaceous biomarkers which can be measured in biological fluid samples to diagnosis or aid in the diagnosis of Alzheimer's disease and distinguish AD samples from non-demented samples.

A method for quantifying a neurodegenerative disorder in a patient that includes obtaining a fluid sample from the subject; measuring a protein biomarker complex in said fluid sample and correlating the measurement with mild cognitive impairment or Alzheimer's disease status. The biomarkers include those that comprise at least one of a transthyretin protein and / or a prostaglandin-H2 D-isomerase protein, and at least one second, different protein selected from a transthyretin, prostaglandin-H2 D-isomerase, beta-2-microglobulin, cystatin C, superoxide dismutase [Cu—Zn], plasma retinol-binding protein, phosphatidylethanolamine-binding protein, carbonic anhydrase 2, prostaglandin-H2 D-isomerase, and / or serotransferrin protein.

The claimed invention describes methods to diagnose or aid in the diagnosis of cancer. The claimed methods are based on the identification of biomarkers which are particularly well suited to discriminate between cancer subjects and healthy subjects. These biomarkers were identified using a unique and novel screening method described herein. The biomarkers identified herein can also be used in the prognosis and monitoring of cancer. The invention comprises the use of leptin, prolactin, OPN and IGF-II for diagnosing, prognosis and monitoring of ovarian cancer.

The present invention relates to a computationally efficient method of finding patterns in any data that can be expressed in the form of arrays of binary features or arrays of categorical features. This includes data represented by continuous-valued attributes that can be transformed to a categorical representation, such as the discovery of patterns of genetic variability that may be causally related to diseases or traits, as well as the discovery of patterns of protein biomarkers that may be used for medical diagnostics, prognostics, and therapeutics. The invention further relates to a program storage device having instructions for controlling a computer system to perform the methods, and to a program storage device containing data structures used in the practice of the methods.

The present invention relates to an immunoaffinity device for capturing one or more analytes present at high or low concentrations in simple or complex matrices. The device is designed as an integrated modular unit and connected to capillary electrophoresis or liquid chromatography for the isolation, enrichment, separation and identification of polymeric macromolecules, primarily protein biomarkers. The integrated modular unit includes an analyte-concentrator-microreaction device connected to a modified cartridge-cassette.
