mRNA sequencing (mRNA-Seq) has become the gold standard for genome-wide gene expression analysis in biomedical research. By enriching poly(A)+ transcripts, researchers can accurately quantify coding RNA and identify differential gene expression across biological conditions.
With the rapid growth of precision medicine, cancer research, immunology, and drug discovery, mRNA-Seq is widely used to understand transcriptional changes underlying disease mechanisms and therapeutic responses.

FAQ
Q1. When should I choose mRNA-seq library preparation?
mRNA-seq is ideal when the primary goal is protein-coding gene expression profiling. It enriches poly(A)+ transcripts, enabling efficient sequencing of coding mRNAs while reducing rRNA background.
Q2. What RNA quality is required for mRNA-seq?
mRNA-seq typically requires high-quality RNA (RIN ≥7) because poly(A) enrichment relies on intact transcripts. Degraded samples may result in biased coverage toward the 3' end.
Q3. Can mRNA-seq detect non-coding RNAs?
mRNA-seq mainly captures polyadenylated transcripts. While some lncRNAs with poly(A) tails may be detected, many non-polyadenylated RNAs are missed.
Q4. What is the main advantage of mRNA-seq?
By removing most rRNA and focusing on poly(A)+ RNA, mRNA-seq provides higher sequencing efficiency and lower required sequencing depth for coding transcript analysis.
