Tru-Q 4 (5% Tier) Reference Standard
The Tru-Q DNA Reference Standards are a highly-characterized, biologically-relevant quality control material used to assess the performance of NGS assays that detect somatic mutations. The specifications of some variants within the Tru-Q product line have been changed for batches manufactured after the 31st March 2021. For more information, please click here.
Next generation sequencing (NGS) platforms give researchers much greater power when profiling tumor samples. However, the use of NGS presents challenges surrounding sample variability, platform bias, and potential failure to detect biomarkers. Horizon’s standards are appropriate for any NGS library preparation including whole-genome, whole-exome, custom capture and targeted amplicon panels. Horizon has developed this Quality-Seq (Q-Seq) NGS Reference Standard range to support the development and continued validation of Next Generation Sequencing platforms. The Tru-Q DNA Reference Standard portfolio covers multiple endogenous SNPs, insertions and deletions. Tru-Q NGS DNA Reference Standard 1 (5% Tier) covers 10 mutations at 5% allelic frequency in genomic DNA format. These may be diluted to even lower allelic frequencies using our Tru-Q 0 Wild Type standard. Furthermore, because the Tru-Q series has 4 different standards at the 5% alleleic frequency range, you may use rotate these as “blinded” samples for proficiency testing in your laboratory. These standards are available only in gDNA format.
With this product you are able to:
- Analyze the sensitivity and specificity of your assay
- Gain certainty of the limit of detection and limit of quantification
- Optimize and validate new cancer panels and routinely monitor the performance of your assay
