Abstract: The present invention relates to a new method for reversible staining and functional isolation or characterization of cells, e.g. antigen-specific T cells. With this technique, the original functional status of cells can be substantially maintained after their identification and purification. Thus, this new method is of broad benefit for basic research and clinical applications.

Abstract: A device and a method for creating and/or maintaining an obstruction free upper airway. The device is configured to fit under the chin of a subject adjacent to the subject's neck at an external location corresponding approximately with the subject's internal soft tissue associated with the neck's anterior triangle. The device is capable of exerting negative pressure on the surface of a subject's neck, displacing the soft tissue forward and enlarging the airway.

Abstract: The present invention relates to cost effective analytical instruments for determining the presence or amount of an analyte in a sample. The analytical instruments utilize an assay cartridge which has a sample receiving port and a rotatable carousel containing a plurality of reagent wells. Each reagent well includes a piston element for delivery of reagent to a test surface. The instrument is capable of indexing the assay cartridge to deliver sample and reagents to a test surface in a predetermined and flexibile manner, thus providing an assay protocol which is specific to the type of sample under analysis. The invention also relates to components, features, disposables, reagent delivery systems, accessories, and methods for using such instruments. Appropriate applications include infectious disease testing, cancer detection and monitoring, therapeutic drug level monitoring, allergy testing, environmental testing, food testing, diagnostic testing of human and veterinary samples, and off-line process testing.

Abstract: The present invention is based on the surprising and unexpected discovery of new and useful polyamide-alkylator conjugates. As a result of their DNA binding properties, polyamides deliver reactive moieties for covalent reaction at specific DNA sequences and thereby inhibit DNA-protein interactions. Thus, site specific alkylation of DNA is a useful tool to regulate gene expression. In addition to competing with transcription factors or promoters, the conjugates of the present invention will be used to target a gene's coding region. This will allow using synthetic chemistry to create a new class of gene specific “knockout” reagents which will be useful in biological disciplines.
