Abstract: The methods provided focus on a quantitative molecular assay tools that systematically measure a set of pre-selected targets, with proper controls in a biological sample for identification of biomarkers or novel targets for a disease status. This allows for systematically maximizing the power of multivariate feature selection tools on the analysis of high-throughput screening data (such as microarray) and use of the well selected target to generate a qPCR array with tissue specific controls and qPCR controls to serve the needs of biomarker study.

Abstract: The methods provided herein use microarray data for feature selection and then use selected targets to generate industry standard qPCR arrays with new clinical sample assay data so order to build a classification model. This multi-step method overcomes the disadvantages of traditional biomarker identification.
