Transcriptome analysis experiments can characterize all 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.
Illumina offers comprehensive next-generation sequencing (NGS) and array solutions that provide high-quality gene expression and transcriptome analysis data for a broad range of sample types. NGS-based RNA sequencing (RNA-Seq) methods can detect and quantify any active gene or transcript, including novel transcripts. Expression microarray technology measures the relative activity of known, predefined genes and transcripts.
RNA-Seq provides a unique combination of transcriptome-wide coverage, sensitivity, and accuracy for a comprehensive view of gene expression changes. Illumina RNA-Seq solutions provide precise measurement of strand orientation, uniform coverage, and high confidence mapping of alternate transcripts and gene fusions. Discover novel gene isoforms, profile expression of select target genes or the whole coding transcriptome, and accurately perform transcript abundance and fold-change measurement.
