    摘要: The location at which tissue samples are obtained to determine whether cells exhibit characeristics associated with cell differentiation or cancer by molecular analysis is determined by topically applying to epithelial tissue a dye that selectively stains cancer and precancerous tissue.

    摘要: A method for chemical fixation of tissues by exposing the tissue to a chemical fixative agent, under oxidative conditions. The chemical fixative agents useable in this method include aldehydes (e.g., formaldehyde, glutaraldehyde, dialdehyde starch), isocyanates (e.g., hexamethylene diisocyanate) and certain polyepoxy compounds (e.g., DENACOL). The oxidative conditions may be provided by heating of a chemical fixative solution that contains the crosslinking agent, in the presence of room air or oxygen. Alternatively, the oxidative conditions may be provided by adding one or more oxidizing chemicals (e.g., hydrogen peroxide or other peroxides, sodium periodate or other periodates, diisocyanates, halogens, n-bromosuccinimide or other halogenated compounds, permanganates, ozone, chromic acid, sulfuryl chloride, sulfoxides, selenoxides, etc.) to the chemical fixative solution. Alternatively, the oxidative conditions may be provided by irradiation (e.g., alpha, beta, ultraviolet, electron beam, gamma rays) of the fixative solution in the presence of room air or oxygen.

    摘要: A method for quantitatively determining the level of protein kinase C (PKC) activation in cells in response to exposure to a PKC activating compound using a moving optical gradient including the steps of providing a series of cell samples, exposing the series of cell samples to different concentrations of the PKC activating compound, moving the cells and the optical gradient relative to each other so as to cause displacement of at least some of the cells, measuring the displacement of at least a portion of the displaced cells for each of the different concentrations, generating a dose response curve of the measured displacement as a function of the concentration of the PKC activating compound, and determining the potency of the PKC activating compound from the dose response curve. The method can also be used to determine the relative efficacy of the PKC activating compound as compared to a standard compound.

    摘要: The stabilization of biomaterials such as proteins in a nominally dry, hydrophilic glassy matrix is vastly improved by the addition of an appropriate amount of a small-molecule pasticizer such as a glycol or DMSO to the formulation, while maintaining a glass transition temperature (Tg) that is above the storage temperature. By plasticizing the glasses, their ability to preserve proteins is improved by as much as 100 times over the unplasticized glass at room temperature. The plasticizer confers the greatest beneficial effect when it is dynamically coupled into the bulk glass, and this coupling occurs over a fairly narrow range of plasticizer concentration. Methods are described in which a small-molecule plasticizer can be incorporated into a glass made of much larger molecules (e.g. a polymeric glass), with desired dynamic coupling, via a molecule that is believed to act as a dynamic linker. Protein preservation data was obtained from two enzymes, horseradish peroxidase (HRP) and alcohol dehydrogenase (ADH).

    摘要: A method and apparatus are disclosed for a high-throughput, large-scale molecular profiling of tissue specimens by retrieving a donor tissue specimen from an array of donor specimens, placing a sample of the donor specimen in an assigned location in a recipient array, providing substantial copies of the array, performing a different biological analysis of each copy, and storing the results of the analysis. The results may be compared to determine if there are correlations or discrepancies between the results of different biological analyses at each assigned location, and also compared to clinical information about the human patient from which the tissue was obtained. The results of similar analyses on corresponding sections of the array can be used as quality control devices, for example by subjecting the arrays to a single simultaneous investigative procedure. Uniform interpretation of the arrays can be obtained, and compared to interpretations of different observers.
