Each single-stranded RNA transcript in a cell is synthesized from one of the two strands of DNA. During RNA library preparation, the RNA transcript is copied back into complementary DNA (cDNA). Strand-specific RNA library preparation improves RNA-seq by accurately identifying antisense transcripts and non-coding RNA and distinguish the boundaries of closely situated or overlapping genes.
Roche’s RNA library preparation kits offer stranded and streamlined workflows for a wide a wide variety of RNA-seq applications, including whole-transcriptome sequencing, tumor profiling using degraded inputs, and sequencing of blood-derived RNA.
