Long non-coding RNAs (lncRNAs) are transcripts longer than 200 nucleotides that regulate gene expression and chromatin organization. With the development of RNA-Seq technologies, lncRNA research has expanded in cancer biology, epigenetics, and precision medicine.

Because many lncRNAs are low-abundance transcripts, library preparation quality is critical for accurate detection.

FAQ
Q1. What is total RNA sequencing?
Total RNA-seq captures all RNA species in a sample after rRNA removal, including mRNA, lncRNA, circRNA, and other non-coding RNAs.
Q2. When should I choose total RNA-seq instead of mRNA-seq?
Total RNA-seq is recommended when studying global transcriptome profiles, RNA processing, or when investigating coding and non-coding RNA simultaneously.
Q3. Does total RNA-seq require more sequencing depth?
Yes. Because total RNA-seq includes a broader range of RNA species, it often requires higher sequencing depth compared to mRNA-seq.
Q4. What samples are suitable for total RNA-seq?
Total RNA-seq works well for degraded samples, FFPE tissues, and complex transcriptome studies, especially when rRNA depletion strategies are used.
