Data analysis is crucial for the successful completion of your Next Generation Sequencing (NGS) project.

This is why you should use Total Transcriptome:

Gene-expression analysis generally is performed on protein-coding RNA, selected from the total RNA pool by their poly-A tail . With Total Transcriptome, you extend your vision towards all transcripts, including long non-coding RNA (lncRNA) or other regulatory RNA species.

Total RNA sequencing helps you to overcome common causes for RNA degradation, such as FFPE-fixation and laser-capture methods. Additionally, this is the safest route towards analysis of samples of varying quality.  Your cohort might not be handled optimally, blocking the only source to obtain transcriptome profiles for your study. Our scientists have set up validated procedures to analyze these challenging samples. This includes clinical-grade sample isolation from FFPE material and tailored data-analysis.

A ribosomal RNA (rRNA) depletion step is included in Total Transcriptome analysis, since the 16S and 18S ribosomal subunits make up ~60-90% of all RNA species present in your sample. You make better use of the sequencing space by removing them at the sample preparation phase. What remains is messenger RNA, and other types of RNA such as long non-coding RNAs (lncRNAs).

This amount is sufficient for performing a statistically sound transcriptome analysis. It is a  more accurate and complete alternative for micro-array sequencing. Contact customer support if you require another amount of reads per sample.

  • Structural variant analysis

To determine all structural variants, such as isoforms, splice variants and gene-fusions we advise a sequencing depth of 80 – 120 million reads per sample. You will receive a full transcriptome analysis, as wells as a reliable overview of SNPs and structural rearrangements.

Data quality 5 01 Product page   Total Transcriptome

The specifications of the data-set that you can expect are listed in your personal quotation. Generally, the sequencing quality score (Q score; ≥30 represents high quality) must be ≥80% for PE 150 reads (Illumina’s official guarantee ≥75%). Our average score of 2018 was Q30 ≥ 90%.
