    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.
