    摘要: Systems, methods and kits that utilize uniquely coded microparticles for performing protein assays are provided. The uniquely coded microparticles are used as a substrate for reverse protein delivery into cells. The microparticles and methods offer the possibility of studying the biological functions of either a single protein of interest in multiple cell types per assay or multiple proteins in a single cell type.

    摘要: The present invention includes several methods for modifying the current processes of manufacturing optical sensing microplates that use continuous waveguide films to reduce/eliminate crosstalk between the biosensors that are incorporated within wells. The methods include (1) physically deteriorating/removing the waveguide film between individual biosensors; (2) chemically depositing highly absorbing materials within the waveguide film between individual biosensors; (3) patterning disordered (scattering) regions between the diffraction gratings that define individual biosensors; (4) using a specific mask and depositing individual patches of waveguide film, where each patch defines at least one biosensor. Each of these methods and several other methods described herein prevent the propagation of light between individual sensing regions, thereby eliminating optical crosstalk between the biosensors. The present invention also includes the resulting microplate.

    摘要: The present invention includes a system and method that uses optical LID biosensors to monitor in real time agonist-induced GPCR signaling events within living cells. Particularly, the present invention includes a system and method for using an optical LID biosensor to screen compounds against a target GPCR within living cells based on the mass redistribution due to agonist-induced GPCR activation. In an extended embodiment, the present invention discloses different ways for self-referencing the optical LID biosensor to eliminate unwanted sensitivity to ambient temperature, pressure fluctuations, and other environmental changes. In yet another extended embodiment, the present invention discloses different ways for screening multiple GPCRs in a single type of cell or multiple GPCRs in multiple types of cells within a single medium solution. In still yet another extended embodiment, the present invention discloses different ways to confirm the physiological or pharmacological effect of a compound against a specific GPCR within living cells.

    摘要: An article for culturing cells includes a substrate on which cells can be cultured. The substrate has a base surface. An array of projections extends from the base surface. The projections have a height of about 1 micrometer to about 100 micrometers, and have a gap distance along the major surface from center to center between neighboring projections of about 10 micrometers to 80 micrometers. A plurality of arrays of projections may extend from the surface with gaps in the base surface between the arrays. Hepatocytes cultures on such microprojection array substrates maintained in vivo like morphology and membrane polarity. Hepatocytes co-cultured with helper cells on such substrates tended to grow in the area of the arrays, while the helper cells tended to grow in the areas between the arrays.

    摘要: The present invention provides a method for preparing a physically stable array of biological membranes, including membrane proteins, on a surface, and the resultant article of manufacture. The method comprises providing a substrate; creating either a polar surface or reactive surface by coating the substrate with a material that either: (1) enhances the stability of lipid spots during withdrawing through a water/air interface and washing and drying protocols; or (2) gives rise to minimal non-specific binding of a labeled target to a background surface, and high specific binding to a probe receptor in said membrane array, or (3) both; and depositing an array of biological-membrane microspots on the substrate. The method may further comprise applying a reagent that includes a soluable protein to stabilize the biological membranes on the surface. Also provided is an article having biological-membrane microspots that are associated in a stable fashion with a substrate surface embodying these properties.
