Gene expression analysis simultaneously compares the RNA expression levels of multiple genes (profiling) and/or multiple samples (screening). This analysis can help scientists identify the molecular basis of phenotypic differences and to select gene expression targets for in-depth study.
Such gene expression differences can lead to potential biomarker discovery for a particular disease phenotype and enable further biomarker validation. Gene expression analysis provides valuable insight into the role of differential gene expression in normal biological and disease processes and in the identification and verification of biomarker signatures.

Transcriptome sequencing by next-generation sequencing enables the discovery of differentially expressed genes using a hypothesis-neutral approach.
Multiplex hybridization-based assays utilize a branched DNA technology for signal amplification for the direct quantitation of gene expression transcripts. These assays are designed to quantitatively measure RNA directly from cell or tissue homogenates without RNA purification or enzymatic manipulation.
Gene expression quantification by digital PCR
Digital PCR enables highly precise measurements and is able to resolve gene expression level changes of two-fold or less. Digital PCR can also be used to determine the absolute quantification of a transcript without the need for a reference gene.
