mRNA Sequencing (mRNA-seq)

Introduction to mRNA Sequencing

Messenger RNA sequencing (mRNA-seq) has revolutionized the exploration of cellular functionality, offering researchers unparalleled insights into the transcriptional landscape of cells. By leveraging high-throughput and precise next-generation sequencing (NGS) techniques, RNA-seq unveils gene expression profiles and highlights the dynamic variations within the transcriptome. This innovative technique selectively captures or enriches single-stranded messenger RNAs (mRNAs), converting them into complementary DNA (cDNA) for streamlined library preparation.

At Novogene, we employ cutting-edge Illumina NovaSeq platforms for sequencing cDNA libraries. These platforms utilize a paired-end 150 bp sequencing strategy, providing high-quality short-read data. Leveraging our extensive experience and robust sequencing capacity, Novogene offers a diverse range of services to meet various research objectives. Our offerings extend beyond eukaryotic mRNA sequencing (mRNA-seq). Novogene can also deliver data on prokaryotic transcripts, non-coding RNAs, full-length isoforms (long-reads), whole transcriptomes, and meta-transcriptomes.

    Project Workflow of Novogene mRNA-seq Services

    The project workflow at Novogene for mRNA-seq services begins with Sample Quality Control (Sample QC), ensuring that the provided samples meet the stringent criteria of the RNA-Seq technique. Following this, tailored libraries are meticulously crafted based on the target organism and application, with the library’s quality assessed through Library QC. Subsequently, a 150 bp paired-end sequencing strategy, employing Illumina PE150 technology, captures the essence of the samples. The resulting data undergoes thorough quality checks (Data QC), and our experienced bioinformaticians perform in-depth analyses to extract valuable insights. The culmination of this journey is the delivery of comprehensive, publication-ready results.
