RNASeq libraries

Does the sequence provider check the quality of the RNA?

Yes, they should check the quality of the RNA.
Nucleomics Core (VIB) performs the following quality checks:

Nanodrop:  

  • OD 260/280 > 1.8
  • OD 260/230 > 1.8

Agilent Bioanalyzer:  

  • Integrity of RNA
  • Contamination with rRNA
