Publication number: 20100016172Abstract: The invention provides reliable, reusable materials, system and methods for use in nucleic acid binding assays between a nucleic-acid binding assay molecule and a robust unimolecular target. In a preferred embodiment, the target is a nucleic acid-containing molecule, L1-X1-L2-X2 (where L1 is the linker to the solid support, and L2 is the linker between the two nucleotide-pairing regions, X1 and X2; L2 folds such that double-stranded DNA structure forms between X1 and X2). L2 is a polynucleotide three nucleotides in length, having the sequence GNA, where N is A, G, C, T, or U. A typical assay uses a target array, where multiple targets are bound to a solid surface. The linker, L1, of the nucleic acid target to the supporting surface is useful although it is significantly longer than suggested in the art. The length of L1 is preferably 8 to 30 nucleotides in length, more preferably from 10 to 20 nucleotides.Type: ApplicationFiled: January 16, 2008Publication date: January 21, 2010Inventor: Aseem Z.
