Horizon DNA standards eliminate the variability associated with patient-derived reference standards, and avoid the hassle of sourcing, characterizing, and documenting your own cell line mixes. The standard is provided at an allelic frequency of 50%, and may be diluted using the corresponding wild-type standard to generate a lower allelic frequencies for limit of detection studies. Horizon’s Base-Seq products are all derived from human cell lines, and are high molecular weight DNA. This format ensures that they may be applied to a wide-range of assays including qPCR, Sanger sequencing, next-generation sequencing, mass array, and more.
With this product you are able to:
- Analyze the sensitivity of your assay
- Gain certainty of the limit of detection
- Optimize and validate new cancer panels and routinely monitor the performance of your assay
