**What you need to provide to the platform to prepare a standard Illumina TruSeq totalRNA library:**
|
|
|
|
|
|
|
|
1. **1µg** of high quality total RNA in a maximum volume of **10µl**. Attention should be payed to DNA contamination as this can interfere with a correct RNA quantification.
|
|
|
|
2. If possible, a **separate aliquot of 2,5** µl of the same RNA preparation taken at the time of the preparation of the sample.
|
|
|
|
3. The concentration of RNA in your sample and the 260/280 and 260/230 nm UV ratios (nanodrop)

Before starting the library prep we will perform a QC (RIN score) on an Agilent BioAnalyser using the 2.5µl aliquot. The main sample is stored at -80°C until all RNA samples have passed QC. If the RIN-score is below 8 we will contact you and determine with you if you need/can provide a new sample, or if we proceed with the current sample.
|
|
|
|
A RIN score below 8 can affect the quality of the obtained results. If no better sample can be obtained, an library prep adapted to degraded samples can be used. Please contact the genomics platform in this case

If obtaining the required amount of RNA is difficult, other types of library prep kits can be used. Please contact the genomics platform in this case. |
