  • Patent number: 10551395
    Abstract: Processing specimens in an automated histological staining system comprising robotically moving a slide carrier into a stainer of the system, the slide carrier carrying slides which respectively carry the specimens, and the specimens being at least partially embedded in paraffin. Liquids are automatically dispensed onto the slides according to a predetermined recipe for at least deparaffinizing, staining, and counterstaining the specimens. The slide carrier can be robotically moved out of the stainer after automatically dispensing the liquids. In some embodiments, a total of all liquid dispensed onto the slides after moving the slide carrier into the stainer and before moving the slide carrier out of the stainer has a greater volumetric concentration of polyol than of monohydric alcohol.

  • Patent number: 10542891
    Abstract: A non-invasive measurement of biological tissue reveals information about the function of that tissue. Polarized light is directed onto the tissue, stimulating the emission of fluorescence, due to one or more endogenous fluorophors in the tissue. Fluorescence anisotropy is then calculated. Such measurements of fluorescence anisotropy are then used to assess the functional status of the tissue, and to identify the existence and severity of disease states. Such assessment can be made by comparing a fluorescence anisotropy profile with a known profile of a control.
