20080213481 | Method for creating a reference region and a sample region on a biosensor - A method is described herein that can use any one of a number of deposition techniques to create a reference region and a sample region on a single biosensor which in the preferred embodiment is located within a single well of a microplate. The deposition techniques that can be used to help create the reference region and the sample region on a surface of the biosensor include: (1) the printing/stamping of a deactivating agent on a reactive surface of the biosensor; (2) the printing/stamping of a target molecule (target protein) on a reactive surface of the biosensor; or (3) the printing/stamping of a reactive agent on an otherwise unreactive surface of the biosensor. | 09-04-2008 |

20090215650 | SUBSTRATES WITH STABLE SURFACE CHEMISTRY FOR BIOLOGICAL MEMBRANE ARRAYS AND METHOD FOR FABRICATING THEREOF - 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. | 08-27-2009 |
20090247427 | LABEL-FREE HIGH THROUGHPUT BIOMOLECULAR SCREENING SYSTEM AND METHOD - A screening system and method are described herein which provide a unique and practical solution for enabling label-free high throughput screening (HTS) to aid in the discovery of new drugs. In one embodiment, the screening system enables direct binding assays to be performed in which a biomolecular interaction of a chemical compound (drug candidate) with a biomolecule (therapeutic target) can be detected using assay volumes and concentrations that are compatible with the current practices of HTS in the pharmaceutical industry. The screening system also enables the detection of bio-chemical interactions that occur in the wells of a microplate which incorporates biosensors and surface chemistry to immobilize the therapeutic target at the surface of the biosensors. The screening system also includes fluid handling and plate handling devices to help perform automated HTS assays. | 10-01-2009 |
20100184626 | ARRAYS OF BIOLOGICAL MEMBRANES AND METHODS AND USE THEREOF - The present invention overcomes the problems and disadvantages associated with prior art arrays by providing an array comprising a plurality of biological membrane microspots associated with a surface of a substrate that can be produced, used and stored, not in an aqueous environment, but in an environment exposed to air under ambient or controlled humidities. Preferably, the biological membrane microspots comprise a membrane bound protein. Most preferably, the membrane bound protein is a G-protein coupled receptor, an ion channel, a receptor serine/threonine kinase or a receptor tyrosine kinase. | 07-22-2010 |

20130071916 | SYNTHETIC COATING FOR CELL CULTURE - A method for coating a surface of a cell culture article includes dissolving a polymer having a covalently attached polypeptide in an aqueous solution to produce a polymer solution. The polymer is formed from monomers selected to form a polymer having a linear backbone, wherein the polymer is crosslink free. The weight percentage of the polypeptide relative to the polymer conjugated to the polypeptide is sufficiently high to render the polymer conjugated to the polypeptide water soluble. The aqueous solution is substantially free of organic solvents. The method further includes (i) disposing the polymer solution on the surface of the cell culture article to produce a coated article; and (ii) subjecting the coated article to sufficient heat or electromagnetic radiation to attach the polymer conjugated to a polypeptide to the surface of the cell culture article. | 03-21-2013 |
