Automated Nucleic Acid Sample Quality Control in NGS Workflows

A 70

The dilution series showed that DV200 evaluation
is most precise when measuring above the lower
limit of the specified assay concentration range,
data not shown.

Sample 1

A dilution series for three individual FFPE RNA
samples was analyzed with the RNA and High
Sensitivity RNA ScreenTape assays to determine
the consistency of the DV200 analysis (Table 1).
Both the RNA ScreenTape and High Sensitivity
RNA ScreenTape assay yielded comparably high
DV200 precision of less than 5 % CV.

Sample 3

A set of three FFPE RNA samples, kindly provided
by the tissue bank of the National Center for
Tumor Diseases (NCT, Heidelberg, Gemany) with
five individual replicates was used to verify the
reproducibility of the DV200 with the RNA and the
High Sensitivity RNA ScreenTape assay. Both
assays showed high reproducibility with a CV
of less than 5 % (Figure 2).
