Transcriptome analysis experiments enable researchers to characterize transcriptional activity (coding and non-coding), focus on a subset of relevant target genes and transcripts, or profile thousands of genes at once to create a global picture of cell function. Gene expression analysis studies can provide a snapshot of actively expressed genes and transcripts under various conditions.
Next-generation sequencing (NGS) capabilities have shifted the scope of transcriptomics from the interrogation of a few genes at a time to the profiling of genome-wide gene expression levels in a single experiment. Find out how to analyze gene expression and identify novel transcripts using NGS-based RNA sequencing (RNA-Seq) methods. Illumina offers comprehensive solutions for a broad range of sample types.
RNA-Seq provides a unique combination of transcriptome-wide coverage, sensitivity, and accuracy for a comprehensive view of gene expression changes. Illumina RNA-Seq methods provide precise measurement of strand orientation, uniform coverage, and high confidence mapping of alternate transcripts and gene fusions. Discover novel gene isoforms, profile gene expression for select targets of interest, analyze the coding transcriptome, and accurately measure transcript abundance and fold changes in expression.

While gene expression microarrays are effective for identifying the expression of known genes and transcripts, they cannot detect previously unidentified transcripts. In contrast, RNA-Seq offers a comprehensive solution for analyzing gene expression, allowing researchers to detect both known and novel genes and transcripts in a single assay.
