    摘要: A planar, rigid substrate made from a porous, inorganic material coated with cationic polymer molecules for attachment of an array of biomolecules, such as DNA, RNA, oligonucleotides, peptides, and proteins. The substrate has a top surface with about at least 200 to about 200,000 times greater surface area than that of a comparable, non-porous substrate. The cationic polymer molecules are anchored on the top surface and in the pores of the porous material. In high-density applications, an array of polynucleotides of a known, predetermined sequence is attached to this cationic polymer layer, such that each of the polynucleotide is attached to a different localized area on the top surface. The top surface has a surface area for attaching biomolecules of approximately 387,500 cm2/cm2 of area (˜7.5 million cm2/1×3 inch piece of substrate). Each pore of the plurality of pores in the top surface of the substrate has a pore radius of between about 40 Å to about 75 Å. Not only does the cationic coating in and over the pores of the substrate greatly increase the overall positive charge on the substrate surface, but also given the size of the pores provides binding sites to which biomolecules can better attach.

    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.
