Abstract: A method includes coupling a molecular diagnostic test device to a power source. A biological sample is conveyed into a sample preparation module. The device is then actuated by only a single action to cause the device to perform the following functions without further user action. First, the device heats the sample via a heater of the sample preparation module to lyse a portion of the sample. Second, the device conveys the lysed sample to an amplification module and heats the sample within a reaction volume of the amplification module to amplify a nucleic acid thereby producing an output solution containing a target amplicon. The device then reacts, within a detection module, each of (i) the output solution and (ii) a reagent formulated to produce a signal that indicates a presence of the target amplicon within the output solution. A result associated with the signal is then read.

Abstract: Disclosed are data processing and analysis methods for gene expression data for identifying endogenous reference genes and a composition for the quantitative analysis of gene expression, comprising a pair of primers and/or probes useful in amplifying the identified endogenous reference genes. Introduced with the concepts of “Zero's proportion” and CV, the method allows different datasets to be integrally analyzed, thereby searching for novel reference genes. By the method, 2,087 genes are first found as housekeeping genes which are expressed in most tissues, and the usefulness thereof in the relative quantification of different target genes is determined by analyzing their expression stability. Of the 2,087 genes, 13 genes show higher expression stability with lower expression levels across a wide range of samples than traditional reference genes such as GAPDH and ACTS, and therefore are suitable for the normalization of universal genes having relatively low expression levels.
