Abstract: Video recordings from two or more optical channels are produced, processed, and analyzed simultaneously in order to provide quantitative analysis of action potentials, calcium transients and ionic flux in excitable cells loaded with voltage or ion sensitive dyes with distinct excitation and emission wavelengths. The specific wavelengths of fluorescent light emitted from each dye are separated and recorded. The recordings are mutually registered and cytometric analysis is performed to provide a quantitative analysis of the action potentials, calcium transient, and/or ionic flux on a cell-by-cell and well-by-well basis in microtiter plates. The cells are then fixed, labeled for other biomarkers, and scanned again. The resulting fixed cell images are registered with the live cell recordings and analyzed; missing cells that were washed off are detected relative to the live recordings, and cytometry data from live and fixed cell scans is collated cell-by-cell.

Abstract: Multifunction autofocus for automated microscopy includes automatic coarse focusing of an automated microscope by reflective positioning, followed by automatic image-based autofocusing of the automated microscope performed in reference to a coarse focus position. In some aspects, the image-based autofocusing utilizes astigmatism in microscope optics for multi-planar image acquisition along a Z axis direction of a microscope. In some other aspects, the image-based autofocusing utilizes astigmatism in microscope optics in combination with chromatic aberration for multi-planar image acquisition along the Z axis direction.

Abstract: An analytical reference for digital histochemistry is constituted of an on-slide standard used to calibrate biomarker expression in biopsy material and tissue sections. The standard consists of one or more calibration standards, which are derived from cell lines that express biomarkers, and are arranged into a calibration array. Expression of the desired biomarkers is validated by Western blotting, flow cytometry, or other methods. The calibration array is applied to a microscopy slide in such a manner that test samples from biopsies or tissue sections, or other cellular material, can also be mounted on the same slide, adjacent to the calibration array. Data obtained from the calibration array can be used to quantify expression of biomarkers in the biopsy, material, tissue sections, tissue microarrays, and cellular material, via digital histochemistry.

Abstract: A system, a method, and a programmed device for measurement of translocational activity among cellular compartments process magnified images of cellular material exposed to an agent by segmenting and compartmentalizing the images and then measuring fractional localized intensity of two or more compartments in the segmented, compartmentalized image. The measured fractional localized intensities are compared to determine translocation of cellular material among the measured components caused by the agent.

Abstract: A system, method and kit for processing an original image of biological material to identify certain components of a biological object by locating the biological object in the image, enhancing the image by sharpening components of interest in the object, and applying a contour-finding function to the enhanced image to create a contour mask. The contour mask may be processed to yield a segmented image divided by structural units of the biological material.
