The progressive library preparation of Novogene’s lncRNA-seq service enables information enrichment and gene expression profiling for both coding and non-coding transcripts from a highly sensitive transcriptomic perspective. Through the application of bioinformatics analysis, the strand orientation and the regulatory association between lncRNA and targeted mRNA can be investigated, all in a single run.
Applications
- LncRNA-seq has been opening new and exciting research possibilities, including:
- Profiling known and novel transcripts and identifies variations
- Predicting target genes of lncRNA
- Identifying biomarkers for cancer/disease diagnostics and classification
- Discovering regulation between lncRNA and mRNA

Project Workflow
The workflow of the lncRNA-seq starts with sample preparation and quality control. The ribosomal RNA (rRNA) is depleted for target transcript enrichment. The fragmented RNA undergoes reverse transcription into cDNA. Strand-specific libraries (also known as stranded libraries, directional libraries) are prepared, and the sequencing is performed using a paired-end 150bp strategy on the Illumina platform. The downstream processing follows the well-established Novogene pipeline, which guarantees the highest quality results. Customized bioinformatics solutions are available upon request.
