KRAS G12S Reference Standard, 50% 1 FFPE curl
The KRAS G12S Reference Standard is a highly-characterized, biologically-relevant quality control material used to assess the performance of assays that detect somatic mutations, such as Sanger and qPCR sequencing assays.
Horizon FFPE 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 and validation of your pre-analytical phase of the workflow. Horizon’s Base-Seq products are all derived from human cell lines. Using a proprietary method of mild fixation and homogenous paraffin embedding, we generate highly-reproducible and consistent FFPE curls. With any commercially available FFPE extraction protocol, our standards yield high molecular weight DNA. This format ensures that they may 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:
- Evaluate of workflow integrity from pre-analytical DNA extraction to post-analytical bioinformatics
- Analyze the sensitivity of your workflow
- Optimize and validate new cancer panels and routinely monitor the performance of your assay
