Abstract: The invention provides a method termed protein retention ExM (proExM), in which proteins, rather than labels, are anchored to the swellable gel, using a cross-linking molecule. This proExM strategy can be used to perform nanoscale imaging of immunostained cells and tissues as well as samples expressing various FPs as fluorescent signals from genetically encoded fluorescent proteins and/or conventional fluorescently labeled secondary antibodies and streptavidin that are directly anchored to the gel are preserved even when subjected to the nonspecific proteolytic digestion.

Abstract: Contemplated test kits and methods for food sensitivity are based on rational-based selection of food preparations with established discriminatory p-value. Particularly preferred kits include those with a minimum number of food preparations that have an average discriminatory p-value of ?0.07 as determined by their raw p-value or an average discriminatory p-value of ?0.10 as determined by FDR multiplicity adjusted p-value. In further contemplated aspects, compositions and methods for food sensitivity are also stratified by gender to further enhance predictive value.

Abstract: Methods and apparatus for assaying the level of analytes in a sample, related to VLA-4, are disclosed. A method of decreasing the level of an anti-integrin antibody in a subject is described including a) contacting a biological sample from a subject with a detectable capture agent associated with a substrate, wherein the capture agent can bind an anti-integrin antibody in the sample; b) detecting binding of the capture agent with the level of the anti-integrin antibody; and c) treating the subject with plasma exchange until the level of the anti-integrin antibody in the sample reaches a predetermined level.

Abstract: This disclosure provides high throughput immunoblot methods and apparatus for an antigen such as a chemical compound, a peptide, a nucleic acid, or a protein released from cells or virus particles in situ. The method yields highly sensitive and accurate results and is useful in analyze complex system including an antigen from cell or tissue lysate.
Abstract: A sample analysis device used to detect a level of exposure of organophosphorus within a sample comprising a sample collection pad, at least one conjugate zone comprising an anti-analyte antibody that is conjugated with a reporter label, and a control antibody that is conjugated with a reporter label, a blocking and/or test zone comprising an immobilized nanoparticle or other molecule that captures the Organophosphate-bound analyte, a second blocking and/or test zone comprising an immobilized antibody that binds to the unbound analyte and an optional third blocking and/or control zone comprising an immobilized antibody that binds to the control molecule wherein, when the analyte is bound by the Organophosphate in the sample it will bind to the first test line, and if the analyte is “free’ from the Organophosphate it will bind to the second test line, and the control antibody will bind to the control line.

Abstract: A method for providing a assistance for maintaining or improving an individual's wellness, comprising the steps of measuring a presence and/or concentration of one or more biomarkers in a sample from the individual; predicting a wellness need for maintaining or improving the individual's wellness based on the measured presence and/or concentration of the one or more biomarkers, wherein the one or more biomarkers are indicators of the wellness need; and altering the living environment of the individual, providing a wellness product or service to the individual or providing information, guidance or advice to the individual for addressing the wellness need of the individual. A system providing assistance for maintaining or improving an individual's wellness is also provided.
Abstract: The present invention relates to a system, device, and method for the high throughput multiplexed detection of a wide number of compounds. The invention comprises of a microwell array coupled to a capture agent array to form a plurality of interfaces between a microwell and a set of immobilized capture agents. The set of capture agents comprises a plurality of distinguishable features, with each feature corresponding to the detection of a particular compound of interest. In certain embodiments, each microwell is configured to contain a single cell. The invention is therefore capable of performing a high throughput analysis of single cell profiles, including profiles of secreted compounds.
Abstract: The present invention inter alia provides a method, and use thereof, of predicting severe CVD complications such as AMI or CVD death by detecting the lipid concentrations or lipid ratios of a biological sample and comparing it to a control and has identified specific lipid markers that are more specific and sensitive in predicting these CVD complications than currently utilized clinical markers. Also provided is an antibodies towards said lipids, and the use thereof for predicting, diagnosing, preventing and/or treating CVD complications. The invention additionally relates to kits comprising lipids and/or an antibody thereto, for use in the prediction and/or diagnosis of CVD complications.

Abstract: The present mention relates to a method for detecting heart damage in a patient. The invention also relates to methods for treatment of patients identified as having heart damage. The invention further pertains to methods for evaluating the efficacy of an ongoing therapeutic regimen designated to treat a damaged heart in a patient.
Abstract: Methods are provided for estimating the relative amounts of identifiable compartments, such as different types of cells or cell components, within a biological sample. The methods use mass spectrometric analysis to quantitate compartment-specific molecules and thereby allow calculation of the amount of each compartment that is present in a biological sample. The methods can, for example, provide a measurement of hematocrit from a dried blood sample.
Abstract: A qualitative detection system and method for visual verification of the presence of human protein in a biopsy specimen collection bottle is disclosed. The system comprises a lateral flow assay assembly securely contained within the lid of a biopsy specimen collection bottle or secured at the bottom of the bottle. The lateral flow assay assembly comprises components that amplify in color intensity through a chromogenic reaction in the presence of certain proteins. A change in color of the components of the lateral flow assay assembly acts as a visual index to qualitatively confirm the placement of human tissue in the biopsy specimen collection bottle.
Abstract: The present invention encompasses methods of identifying proteins and protein modifications of proteins specifically associated with a chromatin.
