Long non-coding RNAs (lncRNAs) are a moderately abundant fraction of the eukaryotic transcriptome, which are comprised of longer than 200nt non-coding RNAs (ncRNAs) , including lincRNAs (intergenic lncRNAs), intronic, anti-sense, sense and bidirectional lncRNAs, which do not encode proteins. lncRNAs affect multiple cellular functions through their regulation of gene transcription, post-transcriptional modifications, and epigenetics. lncRNA sequencing (lncRNA-seq) is a powerful NGS tool to study functional roles in diverse biological processes and human diseases, such as cancer and neurological disorders.
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.

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.
