A perfusion bioreactor and a method for using the perfusion bioreactor for performing a continuous cell culture are disclosed. The perfusion bioreactor includes an outer vessel having a housing with a gas permeable membrane, an opening and a cavity; an inner vessel within the cavity; and a lid to cover the opening. A porous membrane within the cavity divides the cavity into inner and outer compartments. A fresh media port extends through the outer vessel or the at least one lid to receive a fresh media tube that has an end located in the inner compartment. A spent media port extends through the outer vessel or the at least one lid to receive a spent media tube that has an end located in the outer compartment. A mixer is within the inner compartment, and the porous membrane is attached to an opening within the inner vessel.

Perfusion bioreactor and method for using same to perform a continuous cell culture

Cell culture compositions containing LFM-A13 or a structurally related compound can enhance global hepatic function. For example, LFM-A13 is shown to enhance levels of a broad variety of drug metabolism enzymes, including CYP enzymes, and other hepatic enzymes. LFM-A13 is also shown to promote differentiation of stem cells into hepatocytes. LFM-A13 and structurally related compounds can be used in cell culture to enhance global drug metabolism of liver cells for enhanced in vitro study the effects of drug metabolism on other candidate drug compounds.

Cell culture medium for enhanced hepatocyte function

A lid for a multi-well plate having apertures, each aperture having a gas permeable membrane, and fittings extending from the bottom surface of the lid to fit with a multi-well plate to reduce evaporation of liquid contents from within the wells of the multi-well plate, protect the contents of a multi-well plate from spilling or from mingling with the contents of a neighboring well in a multi-well plate is disclosed. The gas permeable membrane comprises one or more of (i) a continuous or discontinuous thin film associated with each aperture, (ii) a locally-thinned portion of the main body, and (iii) a quantity of material at least partially filling each aperture.

Fitted lid for multi-well plate

A substrate plate or device adapted for use with biological or chemical assays is disclosed. The device may take the form of a multi-well plate having a three-dimensional, porous layer as part of a support surface within each well for immobilizing probe species. The porous layer is characterized as having a plurality of interconnected voids defined by a matrix of contiguous solid material. A method and its variants are also described.

Porous substrate plates and the use thereof

The invention relates to G protein-coupled receptor (GPCR) microarrays on porous substrates for structural or functional analyses of GPCRs, and methods of preparing porous substrate surfaces for receiving membranes that comprise GPCRs. In one embodiment, a GPCR microarray of the invention comprises a membrane adhered to an upper surface of a porous substrate, the membrane spanning across a plurality of pores on the porous substrate to form a plurality of cavities having sufficient geometry to permit entry of assay reagents into each cavity, thereby allowing access of assay reagents to both sides of GPCR in the membrane.

Membrane arrays and methods of manufacture

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.

Assay solution compositions and methods for GPCR arrays

An assay and method for selecting analogs and derivatives of gabapentin based on the compounds inhibitory activity toward MAP kinase and MAP kinase mediated reporter gene expression. The method includes the steps of activating the MAP kinase signaling pathway, detecting the MAP kinase signal, and screening the gabapentin analogs and derivatives for inhibitory activity against the MAP kinase signal.
