QIAseq Targeted RNA Extended Panels have been developed as a Sample to Insight solution for quantitative gene expression profiling using RNAseq. These panels integrate molecular barcode technology and a two-stage PCR-based library preparation to deliver unbiased and accurate quantification for your digital RNA sequencing results.

QIAseq Targeted RNA Panels use a digital sequencing method, whereby a unique 12-base random molecular barcode incorporated into the gene-specific primers (GSP1) is used in the first extension step (after mRNA is converted to cDNA). Thus, every extension event yields a unique combination of molecular barcode and target sequence. At the end of sequencing, the relative amount of each mRNA target is determined by the number of unique molecular barcode-target combinations that were sequenced, thereby eliminating PCR duplicates and amplification bias, resulting in more accurate, unbiased gene expression analysis.
