Title

Towards reliable microarray analysis and design

Abstract

Microarray studies represent an extraordinary advance but are notoriously noisy, produce results hardly reproducible, and are therefore unreliable at best. We present a framework that affords a quantitative quantification of their inherent noise and (in)accuracy and, more importantly, a methodology to remove noise and improve their reliability and reproducibility. Furthermore, we present a principled methodology to design a variant of new generation microarray (nxh-chips) that are provably reliable by two new metrics of reliability. Potential impact is illustrated with a new approach to phylogenetics that produces a universal tree of life (TOL) based on more objective criteria and is feasibly scalable to entire genomes, while being implementable on current microarray biotechnology. A preliminary TOL is actually shown as a phylogenetic analyses of a selection of 22 species/ biomarkers from the standard Biomarker Identification Numbers (BOLD/BINs). Conclusions include some discussion of theoretical and experimental problems for implementation of this methodology in practice.
