  • Patent number: 7817840
    Abstract: Cell based assays are used to assess the hepatotoxicity of a stimulus. Imaging technologies are used to analyze the effects of a stimulus on hepatocytes. Image analysis may characterize the stimulus on the basis of whether it is hepatotoxic, and if so what type of pathology is exhibited; e.g., apoptosis, necrosis, cholestasis, and/or steatosis.

  • Publication number: 20040023261
    Abstract: Methods, compositions and articles of manufacture for encoding a cell with semiconductor nanocrystals and/or other fluorophors are provided. The encoded cells can be subjected to functional assays in mixed populations, and an assay result can be determined and associated with individual cells by virtue of their code. The methods are particularly useful in multiplex settings where a plurality of encoded cells are to be assayed. The methods are used in screening methods for G protein coupled receptors (GPCRs), for identifying the ligands and functions of orphan GPCRs, and for screening for modulators of GPCRs. Kits comprising reagents for performing such methods are also provided.

  • Publication number: 20020164777
    Abstract: A device for measuring electrophysiological properties of a cell membrane of an individual cell comprises a plate provided with at least one opening. The opening is bounded by a surface and the surface is modified, such as via heat treatment, to facilitate formation of a gigaseal. A chamber is adjacent to the plate. The chamber is in fluid communication with at least one opening and is adapted to hold an electrically conductive solution. The plate further comprises a first electrode located in the chamber and a second electrode located adjacent to the plate.

  • Patent number: 6309842
    Abstract: The invention provides methods for screening libraries of complexes for compounds having a desired property, especially, the capacity to agonize, bind to, or antagonize a cellular receptor. The complexes in such libraries comprise a compound under test, a tag recording at least one step in synthesis of the compound, and a tether susceptible to modification by a reporter molecule. Modification of the tether is used to signify that a complex contains a compound having a desired property. The tag can be decoded to reveal at least one step in the synthesis of such a compound.
