Sample Requirement

Concentration and Purity

Use spectrophotometrical method to get the concentration and a ratio (OD260/280 ~2.0 and OD260/230 ~1.8-2.2) of each sample (the ratio shows purity of samples).

Before delivery measure diluted RNA fluorometricly.


Use Agilent Technologies 2100 Bioanalyzer (RIN) or equivalent equipment  for RNA quality/integrity check.

  • mRNA analysis: RIN ≥ 8. If any sample has lower quality score please consult us.
  • total RNA analysis: RIN value is not as crucial. RIN>3.
  • FFPE RNA analysis: DV200 value < 30% is NOT recommended as RNA is too degraded. 

Freeze and thaw samples as few times as possible and work with the RNA on ice to avoid further degradation.

Total RNA amount recommended 

Always dilute samples in nuclease-free ultrapure H2O.





Illumina mRNA analysis

10 ng/μL

110 μL

Illumina TotalRNA analysis

50 ng/μL

25 μL

SMARTer TotalRNA Pico analysis

Should be discussed and
adjusted according to
RNA amount available.

20 uL

Lower concentrations and volumes can be discussed.
