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: The present invention provides a method, system and composition for screening drug candidates for cardiotoxicity and for novel drugs that effect cardiomyocyte contractility and function. The invention provides an efficient and reliable screening assay to detect the effect of new and potential drug candidates on cardiomyocyte calcium flux, membrane depolarization, and/or the propagation of action potentials.
