RNA Sequencing ServicemRNA sequencing (mRNA-Seq), a method of transcriptome profiling based on deep-sequencing technologies, provides a more precise measurement of transcript levels and their isoforms with a complete snapshot of the coding transcriptome than other methods such as microarray analysis. Transcriptome sequencing with longer read length enables the identification of novel transcripts, alternative splicing and gene fusions, and scientists can identify biomarkers or key regulated genes, key functional genes related to different phenotypes, as well as key factors in temporal changes. RNA-Seq quantification with shorter read length can simultaneously measure the expression levels of many transcripts. It is widely used in disease research, drug response research, pharmacokinetics, and personalized healthcare reasearch.

Novogene offers comprehensive transcriptome sequencing and RNA-Seq quantification services using cutting edge Illumina platform and widley accepted analysis software, serving customers with different research emphases. In addition to mRNA sequencing, we offer lncRNA, circular RNA, and small RNA sequencing services. Contact us to learn more.

Project Workflow

RNA Sequencing Service Project Workflow

Sequencing Strategy

  • 250~300 bp insert cDNA library
  • HiSeq platform, paired-end 150 bp (Transcriptome sequencing service)
  • HiSeq platform, single-end 50 bp (RNA-Seq quantification service)

Data Quality Guarantee

  • Our data quality guarantee, as measured by the percentage of bases with a sequencing quality score above Q30 (PE 150, ≥80%; SE 50, ≥90%), exceeds Illumina’s official guarantee (PE 150, ≥75%; SE 50, ≥80%). See examples of our high quality data.

Sample Requirements

For both services:
  • Total RNA amount: ≥ 1.0 μg; RNA concentration: ≥ 50 ng/μl (For human and mouse, 200 ng could be accepted with risk.)
  • RIN value ≥ 6.3 for plants and fungi; RIN value ≥ 6.8 for animals
  • OD260/280 ≥ 2.0, OD260/230 ≥ 2.0, without degradation and DNA contamination
  • FFPE sample: > 10 scrolls or slides. Samples should be tested as pre-qualified by gel electrophoresis before sample submission.

Turnaround Time

  • Within 15 working days from verification of sample quality without data analysis
  • The turnaround for data analysis is project dependent.

Recommended Sequencing Depth

  • ≥ 20 M reads

mRNA and small RNA transcriptomes reveal insights into dynamic homoeolog regulation of allopolyploid heterosis in nascent hexaploid wheat
The Plant Cell, 26:1878-1900 (2014)

As published online in The Plant Cell, Novogene, in cooperation with the Chinese Academy of Agriculture Sciences, reported that mRNA and small RNA transcriptomes provide insights into small RNA–mediated dynamic homoeolog regulation mechanisms that may contribute to heterosis in nascent hexaploid wheat. Expression level dominance, in which genes exhibit the expression levels of a dominant subgenome, was observed for a large number of genes associated with development and adaptation. Results also suggested that microRNAs and small interfering RNAs contribute to the differential gene expression patterns observed in hybrid progeny. The findings advanced our understanding of the regulation of key agronomic traits in a major food crop.
