    摘要： Capture particles for harvesting analytes from solution and methods for using them are described. The capture particles are made up of a polymeric matrix having pore size that allows for the analytes to enter the capture particles. The pore size of the capture particles may be changeable upon application of a stimulus to the particles, allowing the pore size of the particles to be changed so that analytes of interest remain sequestered inside the particles. The polymeric matrix of the capture particles may be made of co-polymeric materials having a structural monomer and an affinity monomer, the affinity monomer having properties that attract the analyte to the capture particle. The capture particles may be used to isolate and identify analytes present in a mixture. They may also be used to protect analytes which are typically subject to degradation upon harvesting and to concentrate low an analyte in low abundance in a fluid.

    摘要： A polypeptide can conduct electricity in a closed circuit. Conformational changes in the polypeptide due to posttranslational modifications or ligand binding can effect the conductive properties of the polypeptide which can be measured. In such a closed circuit, a polypeptide having at least one residue capable of reversible modification can be used as a molecular switch. Circuits comprising such molecular switches can be used, for example, in methods for assessing the modification state of a polypeptide, determining the activity of an enzyme of interest, identifying compounds that affect the activity of an enzyme of interest, storing data, detecting the presence of a compound and identifying inhibitors of protein-protein interactions.

    摘要： This invention relates, e.g., to a composition that, at room temperature, when contacted with a sample comprising phosphoproteins, can fix and stabilize cellular phosphoproteins, preserve cellular morphology, and allow the sample to be frozen to generate a cryostat frozen section suitable for molecular analysis. The composition comprises (1) a fixative that stabilizes the proteins in the sample and that has a sufficient water content for a stabilizer and/or a permeability enhancing agent to be soluble therein; (2) a stabilizer, comprising (a) a kinase inhibitor and (b) a phosphatase inhibitor and, optionally, (c) a protease (e.g., proteinase) inhibitor; (3) a permeability enhancing agent; and (4) lactic acid. Methods and kits are described for preserving phosphoproteins, using such a composition. Also described are endogenous surrogate markers for monitoring protein degradation, including the loss of posttranslational modifications (such as phosphorylation), e.g. following removal of a cell or tissue from a subject; and exogenous molecular sentinels (e.g. phosphoproteins attached to magnetic nanoparticles) that allow one to evaluate the processing history of a cellular or tissue population sample.
