Abstract: In a multiplexed assay method carried out in solution, wherein the solution contains nucleic acid targets and, wherein several different types of oligonucleotide probes, each type having a different sequence in a region designated as a target binding domain, are used to detect the nucleic acid targets, said assay method including a method for increasing the effective concentration of the nucleic acid targets at the surface of a bead to which the oligonucleotide probes are bound, by one or more of the following steps:adjusting assay conditions so as to increase the effective concentration of the targets available for binding to the probes, by one or more of the following: (i) selecting a particular probe density on the surface of the bead; (ii) selecting a solution having an ionic strength greater than a threshold; (ii) selecting a target domain of a size less than a threshold; or (iii) selecting target domains within a specified proximity to a terminal end of the targets.

Abstract: Disclosed are methods of multiplexed analysis of oligonucleotides in a sample, including: methods of probe and target “engineering”, as well as methods of assay signal analysis relating to the modulation of the probe-target affinity constant, K by a variety of factors including the elastic properties of target strands and layers of immobilized (“grafted”) probes; and assay methodologies relating to: the tuning of assay signal intensities including dynamic range compression and on-chip signal amplification; the combination of hybridization-mediated and elongation-mediated detection for the quantitative determination of abundance of messages displaying a high degree of sequence similarity, including, for example, the simultaneous determination of the relative expression levels, and identification of the specific class of, untranslated AU-rich subsequences located near the 3′ terminus of mRNA; and a new method of subtractive differential gene expression analysis which requires only a single color label.
