    摘要: A standardized, buffered solution or “ink” composition for re-formulating or suspending biological membranes used in the fabrication of membrane arrays. The composition can enhance assay performance and prolong the shelf life of biological membrane arrays. The ink composition comprises a combination of at least two of the following six classes of reagents: 1) a pH buffer reagent; 2) a monovalent or divalent, inorganic salt; 3) a membrane stabilizer; 4) a solution viscosity control reagent; 5) a water-soluble protein; or, 6) a protease inhibitor. A method for fabricating a membrane array using the present ink composition is also described.

    摘要: Buffered assay solutions for performing 1) binding or 2) functional assays on GPCR arrays, along with methods for their use are described. The buffered assay solution has an underlying composition having: a buffer reagent with a pH in the range of about 6.5 to about 7.9; an inorganic salt of either a monovalent or divalent species, at a concentration from about 1 mM to about 500 mM; and optionally a combination of: c) a blocker reagent at a concentration of about 0.01 wt. % to about 2 wt. % of the composition, or d) protease-inhibitor at a concentration of about 0.001 mM to about 100 mM. In an embodiment for functional assay uses, the composition is modified to also include a GTP-analogue, a guanosine 5′-diphosphate (GDP) salt, and/or an anti-oxidant reagent.

    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.
