摘要:
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.

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.

Disclosed is a cell culture article including: a substrate; a tie-layer attached to at least the substrate; and a bio-compatible layer attached to at least the tie layer, the bio-compatible layer having been obtained from surface oxidation of a polymer layer. Also disclosed are methods for making the cell culture article and methods for performing an assay of a ligand with the article.
摘要:
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.
